This "capacity" thing is true of pretty much all of power tools...
I'm now debating whether I should buy a bigger chainsaw as I've got a couple
big trees to cut down and my 18" Stihl MS271 (about 3.5 hp) seems
inadequate. Both are about 36" in diameter at chest height, one an ash and
the other a maple. I'm looking at the Stihl MS461... about 6 hp and will
take much longer bars. It's not inexpensive but it would cost way less than
hiring a tree service to take down those two big trees and I'd have it for
other serious tree cutting. I took Game of Logging training, have done a
lot of studying, and have felled quite a number of trees so those big ones
look to be reasonable tasks to me... except for the capacity of my MS271
that is. I've taken down trees taller than those two but not as big in
diameter...

And i remember having to settle for something like 71 octane because
it was all I could get - at $1.65 a liter - back in '74 in Livingstone
Zambia. The old '49 beetle didn't care, but the 204 Peugeot wasn't
happy untill I cranked the timing back. You could drive the stage 3
Mini Moke into the shop with the key turned off after you got it

No, but some of the new 40 volt lithium ion saws will do anything my

hand too close to the muffler. The remington has a bit more "cajones"
than the big partner.

Techron is good, but the "nitrogen enriched" is a LITTLE more than

I don't envision a computer controlled injected 2 stroke chain saw in
the near future - the extra weight and the durability concerns make
it somewhat unlikely in my lifetime for any but the largest
professional saws.
The day of the gasoline consumer saw is likely coming close to an end
with new electric saw technology advancing very quickly.

That very well may be however it is only in the Premium grade Shell
gasoline. Even their web site indicates this.

Techron is not bad at all. I was selling Techron before it was added to
gasoline. I learned about Techron through General Motors, they were
selling it as a fuel additive to combat the injector contamination
issues that they were having in the 80's. And it worked well. It came
in a 16 or 32 oz bottle IIRC. It was only later on that Chevron began
marketing it with their gasoline in Texas.

Absolutely a requirement when they don't know which fuel you are going
to choose. It is a blanket statement that covers all the bases.
Mid grade is blended at the station pump.

The small engine shop that services my equipment tells me that the best
thing to use in those items is the pre-mixed fuel sold in the quart
cans. The reason? It's premium fuel, with stabilizers and NO ALCOHOL.
The last is the biggie. Over time the ethanol added to the fuel will
wreak havoc with your 2-cycle engine. So, you using premium is a good
thing and you can make it better if your state allows for mixtures
without ethanol. I know that Wisconsin does, but Illinois doesn't.

I understand how octane is determined - and since there is no such
thing as more than 100% iso-octane to put in the test mix, 100 octane
is as high, technically, as an "octane rating" can go. From 100 on up
it is "technically" an Anti Knock Index. AKI can also be used below
100.RM/2 is used for automotive motor fuel in North America - but not
for Aviation Gas.
I remember this being taght by the petroleum engineers from Texaco,
Imperial and Shell when I worked for garages that sold those 3 brands
of fuel "way back in the day" between 1968 and 1983. They said
although often refered to as the "octane rating" anything over 100 is
technically the AntiKnock Index, which in Noth America is generally
referred to as "road octane" or "R+M/2" or "pump octane" while
elsewhere in the world it is generally ROM - straight "research
octane"
Octane sensitivity has to do with the difference between research and
motor octanes.
Motor Octane is also sometimes (mistakenly) referred to as "rich"
octane and is the measure of anti-knock qualities under sustained high
load, (accelleration at low RPM) while research octane is sometimes
referred to as "lean" octane - the measure of antiknock qualities
under typical mild driving.(high rpm low load)
They call it sensitivity because it indicates hpw sensitive the fuel
is to varying conditions of tempwrature and load.. Sensitivity of most
automotive gasoline in North America is generally about 10 points.
In europe recently the sensitivity has been higher, (20 points and
more), meaning some fuels (under 105RON)do not meet the required 85?
minimum MON for European regulations.
Lean and Rich octane ratings are used to rate aviation fuel.. They are
similar to the RON and MON , in that rich mixtures are used under high
power settings, and lean under lower power settings. The "sensitivity"
of Avgas is generally closer to 30 points (100-130 for instance for
100LL regular avgas) Lean rating in AvGas is always lower than rich
rating, just as MON is always lower than RON in Mogas. It is a
combination of actual differences in the knock resistance of the fuel
and differences in the measurement protocol that contribute to tne
higher "sensitivity" of AvGas.
The AvGas "lean octane"number is not necessarilly the same as the RON
number would be for the same fuel, but it is close.

Thanks for reminding me of that. After being told of the pre-mix and
using it. I went looking for premium here without success. Found that
very site and, unfortunately, those are all downstate pumps subject to
different regulations which are imposed on us "lucky" devils residing in
NE Illinois. I can, however, head north about 15 miles and get all the
premium, ETOH free gas I want.

Different strokes for different folk, John.
Saw Shell advertising ethanol free premium up in Wisconsin. Not so here
in Illinois (at least not in the NE corner of the state - down south
it's available in some areas).
I think, but not sure, that Shell's ethanol free was tied in to their
"V-Power" blend or somesuch

I do the same. I have a 4 cycle mini-rototiller with a Honda mini engine. It
has been a problem from new, had it serviced and not much better. It was
hard to start and would stall after running a few minutes, and then only run
a minute or so after starting hot. This was with regular 87 gas. I also have
a Honda weed wacker with a mini 4 stroke engine that runs fine with regular
87 fuel.
Switched all my small engines to Shell premium, they run great and even the
difficult mini-rototiller Honda now runs properly with only a change of fuel
to premium.
The added cost of premium is insignificant compared to frequent servicing
required when they don't run properly. By the way, I have a Honda
self-propelled walk behind mower that is now over 25 years old and has never
needed service other than oil changes. It starts on the first pull.

The manual with my saw recommends a minimum of 89 octane... I use ethanol
free premium gas along with synthetic 2 cycle oil (STIHL HP Ultra) that has
fuel stabilizers. In the past year or so one of the chain convenience stores
started carrying ethanol free premium gas and they are adding store
locations steadily over time--I've got one 7/10ths of a mile from my house
now. I started using this mix in all my Stihl 2 stroke equipment (string
trimmer, hedge clipper, chainsaw), and the gas in my mower, and everything
runs better.
I would expect your saw to run cooler, and better, with the premium fuel as
compared to say 87 octane based on my saw's manual:
"Use mid-grade unleaded gasoline with a minimum octane rating of 89 and no
more than 10% ethanol content."
"Fuel with a lower octane rating may increase engine temperatures. This, in
turn, increases the risk of piston seizure and damage to the engine."

OK - when I get the saw out I pull it through once or twice with the
choke on, and the ignition off so it won't tear my arm off - then turn
on the ignition and give it a couple good sharp pulls - Usually
running on the second pull with the ignition on.. Usually barks at me
on the first "powered on" pull. - knock the choke in one notch and
pull again. It either starts or tears the rope out of my hand. I don;t
know if the saw is stock or not - I've only owned it for about 25
years.

I had gas and then electric. I can/could saw 6~8" diameter oak limbs
with no hesitation. Granted that because the electric simply runs
slower than the gas does at full throttle the gas cut faster. But over
all in the past 20 or so years the electric has had much less down time
than the gas did, so in the time spent futzing with the gas saw,
including mixing and filling with gas, the electric required less of MY
time , which IMHO is all that counts. Gas is great when that is all
that will work but with electricity available I will stick with an
electric for any trimming including the use of my electric recip saw for
4" and under branches.

You can use 100ll in your saw - but you will need to tear it down to
remove the lead deposits every hundred hours or so. There is more
lead in 100LL than there ever was in the highest octane automotive
fuel sold retail (like Sunoco 260) by a factor of more than 2.

I don't have all that much experience renting tools (I usually buy)
but when I have, they've always been top-o-the line tools. The
chainsaws and concrete saws (chain saw with cutoff wheel) have all
been Stilhs. Some have been rough aesthetically but functionally in
great shape.

If it's more than a one-time use, it probably does make sense to buy.
A gas tool is a little different, IMO, though. I'd want to make sure I
had use for it several times a year (maintenance and all). I have a
gas power-washer that was probably a bad idea to buy. I don't use it
enough.

Agreed. Sometimes (usually, when it comes to woodworking tools ;-)
justification isn't needed. "I want" is good enough. If this is the
case, here, go for it. OTOH, if it's just one job that needs the
moose-of-a-saw, rent. Again, remember the maintenance. It has to be
done even if the saw isn't used.

In Texas there is more differences in Premium and regular than just
higher obtain. Typically 3 trades of fuel. Regular, often with fewer
detergents and more alcohol. Premium, more detergents and often no
alcohol. Mid grade fuel comes from the regular and Premium tanks.
So If yo want to avoid alcohol in the fuel, which attracts moisture, buy
premium.

I started using Stabil in my gas can and my fuel does well for months on
end, from one season to the next. The label claims that it will keep
the gas good for 2 years, and now I believe it. Still a good idea to
run the carb/tank dry at the end of a season. I only do this however at
the end of the season. Some of my equipment started running badly until
I started treating the gas can about 3 years ago. Now all run
fine...even the Honda that I bought in the spring of 1987.

I think you points would make more sense if you pointed out that gas
works most anywhere and would probably last longer with day to day usage.
The electric that I have cuts much more than "a small limb a couple of
times a year".
I would be willing to bet that if you and I cut down a small tree with
say a 10 diameter trunk, that you probably would not finish far ahead of
me. Many more larger trees and I give you the nod.
I think you vastly under estimate what an electric can do if you believe
that they are only good for a small limb a couple of times a
year. I have owned both and in my yard I would choose electric over gas
if both were sitting on my work bench and ready to go.
Out in the woods felling trees all day long the gas would be an obvious
choice.
I suppose it is a lot like Festool of Fein. Unless you are making money
or specifically have to have the tool it is hard to actually justify the
expense. Then some simply want more than they actually need, and that is
OK too.

The higher end Stihl and Husqvarna professional saws have engine management
systems available that electronically control the ignition timing and fuel
metering... Both claim to compensate for different fuels, altitude,
humidity, temperature and clogged air filters.
Stihl's is called M-Tronic and Husqvarna's is called Autotune.
That said, the average homeowner or farmer probably isn't going to buy one
of those professional saws... they are costly and excessively powerful for
what mere mortals need in a chainsaw. The guys making a living in the woods
or doing serious tree work are more likely to spend the big bucks...

Waste of money. Two stroke engines don't have enough
compression to require premium gas.
If you use the chainsaw frequently, regular gas is fine.
If you use it intermittantly then try to find ethanol-
free gas, since ethanol sitting in the carb will eventually
eat away the insides and you'll need a carb rebuild.
If you can, run it dry when you're done using it,
whichever kind of gas you use.

Regular gas is usually 10% or less ethanol. Exactly how
much depends on whatever other additives they're using,
and the octane rating they want. The reason for putting
ethanol in regular gas is that it's a very effective
octane booster, and unlike other octane boosters such
as MBTE it's more-or-less non toxic.

That sounds about right for E85. Corn alcohol makes
a very poor fuel. With current technology, the only
economically viable (and enviromentally sound) way
to make alcohol fuel is to start with sugar.

You are confusing two different things here, both of
which ethanol happens to be good for.
One is octane rating. Raw gas (no additives) has an octane
rating (*) of around 70, so something has to be added to
raise it to a useful level. Historically that was tetra
ethyl lead, which of course is now banned. Ethanol has an
octane rating of around 110. So adding ethanol to gas is
a very effective way to raise the octane rating.
The second is oxygenation. In ideal conditions there is
enough oxygen in the air entering the engine to completely
burn the fuel. Ideal conditions don't always occur, so
a fuel additive that contains oxygen can help get to
complete combustion. Ethanol contains oxygen, so it is
effective as an oxygenator.
Until 2007 there was a Federal requirement (in the US) to
include oxygenators in fuel. That requirement no longer
exists. The reason ethanol is added to gasoline now is
for it's value as an octane booster.
(* octane rating is a confusing thing, because there are
several common ways of testing it, which give different
numbers. In North America the AKI (or R+M/2) method is
used, which is what the numbers above are based on).

Typically differences in detergents are between brands,
not between fuel grades. The vendors would like you to
think there's extra "good stuff" in premium (especially
now that it costs $0.50 or more above regular), but
other than octane boosters it's generally not so.
I am also dubious that premium would be alcohol-free.
I suspect if it was, it would be prominently advertised,
and I haven't seen that anywhere.

Antiknock Index and Octane Rating are the same thing. You're

yourself in the foot...

It usually is added to premium in the US. I don't know
why Canada is different, but I suspect it's due to tax
policy.
In the US, ethanol is used because:
a) it's an effective octane booster
b) it's cheap compared to the alternatives
c) the energy act of 2007 provides Federal incentives
d) it does not have the legal liabilities of MBTE
Incidently, ethanol isn't "added to gas at 10%". The amount
used varies, from 5% to 10%, depending on the octane rating
desired.

I'm inclined to think that "nitrogen enriched" stuff is all

If you want my opinion, the best gasoline additive is Chevron's
Techron. But I don't think there's much difference between
any of the top brands.

Same here - I think that's a legal requirement, and is the
same wording everywhere in the US.
Next time I'm in Texas I'll have to look at the pumps and see
if the premium is marked different (last time I got gas in TX
was at the Buck-ees north of Houston on US290, and I was so
overwhelmed at the size of it - must have been 100 pumps - I
didn't pay attention to that sort of detail).

Some of that is profiteering, but a big part of it is that
corn ethanol requires a fair bit of fuel to make, and it
can't be stored all that long, so the cost of making it
tracks the cost of fuel fairly well.
In Brazil, where ethanol comes from sugar cane, it takes
much less energy to make it, and almost all comes from
burning bagasse rather than other fuels.

You are confused here.
There are several methods of calculating octane rating,
the two most common being the "research method" and the
"motor method". They work the same way, you run the
fuel being tested in a special motor which has a
variable compression ratio, and compare the point
where preignition starts to the point where it starts
with a particular isomer of heptane (defined as zero
octane rating) and a particular isomer of octane
(defined as 100 octane rating). It's entirely possible
for a fuel to accomdate a higher compression ratio
than the octane standard, in which case it's octane
rating is proportionally greater than 100 (conceptually
it's also possible for a fuel to not reach the compression
ratio of the heptane standard, in which case it would
have an octane rating less than zero).
Now, in the UK and Europe, they use the research method
exclusively. Their octane ratings are always RON (and
they have no such thing as an antiknock index). In
North America they take the average of the research
method and the motor method, and call the result the
"pump octane rating". You'll see this on gas pumps:
(R + M)/2. (there are exceptions in the US - racing
fuel is often specified by RON, and av-gas is specified
by MON).
For simplicity, rather than say "the average of the
research method and the motor method", (R + M)/2 has
also come to be known as the antiknock index, or AKI.
It's just another term for octane rating.

Things have evolved quite a bit... Stihl has some electric saws that would
serve a homeowner well... and one that is marketed to professionals that
draws 15 amps. I've seen electric Sithl saws used indoors along with
electric powered bandsaw mills.

They've got a battery powered saw too which would probably serve a
homeowner's occasional needs (not useful to me though!).

I run nothing but ethanol free premium gas in ALL of my small engine
equipment. For the small amount of fuel I put through them in a year,
the difference in cost is a non-issue, particularly considering the
possible costs of the alternatives. A screwed up carb or a scuffed
piston or siezed engine is too costly to consider trying to save the
7 cents a liter or whatever.

The reason ethanol is added to fuel in North America is NOT for octane
improvement. It is added as an "oxygenator"
It is supposed to reduce the carbon monaxide and particulate emissions
of the vehicle.

on regular gas 14.6 litres per 100 km
on E85 ethanol 21.8 litres per 100 km

This is true but to be clear Tier 1 is not strictly the premium fuel,
rather the brand. Exxon has always had detergents and additives but
only relatively recently has qualified as a Tier 1 provider.
The Top Tier standards must apply to all grades of gasoline that a
company sells, whether it is economy (low-octane) or premium
(high-octane).[2] However, premium gasolines may contain even higher
levels of detergent additives.

high octane fuel does not cause an engine to run hotter, contrary to
common belief. However, running gasahol MAY cause the engine to run
cooler due to reduced energy content. The chances of damage due to
running "hooch" FAR outway any possibility of damage from running
high-test fuel.
If the octane is too low (and adding oil lowers the octane) an engine
will detonate, and detonation transfers more heat to the piston, cyl,
and head by disrupting the "boundary layers" causing the engine to
overheat quickly.
In aircraft, the first sign of incipient detonation is a simultanious
increase in head temperature and drop in EGT (Exhaust Gas
Temperature).
When that happens you have seconds to pull back on the throttle to
avoid engine damage and possible engine failure. Doesn't matter if
it's a 2 stroke ultralight or a 4 stroke Lycosaurus

If you are a "chain saw user" the chances are pretty good you will
use the big saw again if you own it.
If you will never use it again, rent.
If you've been Jonesing for a bigger saw for a while but couldn't
justify the expense, now is the time.

Hydrocracked/catalytic cracked first run gasoline has an octane of up
to 90 with no additives.
There is no such thing as an "octane" rating of over 100. Over 100 it
is an "aki" or antiknock index..

Then why is ethanol added to regular gas at 10% and not added to
premium (in very many cases)???
The ethanol is added to regular gas because that is the easiest way to
sell the volume of ethanol mandated. The total amount of gasoline sold
in an area needs to contain, say, 9% ethanol (maximum limit is 10%)
and 99% of gas sold is regular (or a mix containing regular) so they
do not HAVE to put it in the premium gas.
Also, the ethanol is not added at the refinery (at least in many
cases) it is added to the tanker at the depot - so the regular gas at
the depot has to be 97 octane without ethanol.
I don't "buy" the ethanol as octane booster arguement - at least here
in Ontario. Does it increase Octane? Sure. Is octane the reason it is
added? No. It is added because it is mandated. It is mandated because
it is an oxygenator. The octane boost is just a bonus. (which helps
mitigate thedilution of the fuel energy caused by the dilution of the
fuel with low energy ethanol in the eye of those who don't understand
octane requirements and energy content and the fact they are not
connected in any way)

Shell Canada has gone on record saying there WILL BE no ethanol in
their premium gasoline.
If you look at PurGas.org? the vast majority of stations selling
ethanol free gasoline sell only premium ethanol free gasoline. The
only major resellers of ethanol free regular are marinas.
Mogas for aircraft use is also ethsanol free premium. No Mogas STC
allows ethanol fuel.

Washington allows it. I've found that my ancient 500cc motorcycle gets
50mpg with ethanol, 60 without. And the ethanol does bad things to tank
liners in old bikes.
BTW, eliminating 10% ethanol increases my bikes mileage by 20%. Tell me
how I'm lowering pollution with ethanol :-).

I've had the same chain saw since around 1978. The first tree I cut up
it blew up. My neighbor, a farmer the first 20 years of life, owned a
two man auto repair shop the next 50 years, and a lawnmower repair shop
the next 25 years, told me my mistake was using the 50-1 chainsaw oil
mixture recommend by Sears. He said use regular 20w non-detergent in
something like 9-1 or 20-1, can't recall, it's written on my gas can in
the shed. He said it might smoke a bit, and be hard to start but it
will never freeze up. Arguing with a 95 year old dude that still worked
on small engines 9-9 6 days a week seemed silly, so I gave it a shot.
It was always hard to start, so didn't notice a difference, but learned
to use ether to get er running (even though I was often told ether would
hurt the engine)
I rebuilt the engine, took his advice, and now, almost 40 years later,
the saw still runs great. I haven't used it much lately, getting old,
but last I used it it still ran, and smoked like a champ...
Also, as far as premium gas in a chainsaw, my guess is once you dump oil
in the gas, it doesn't matter much.

I use only ethanol free gas for all of my small engines and my farm tractor.
Around here the only ethanol free gas you can get is Premium. I've never
noticed any difference in how hot my engines run on it, and I have two Stihl
chainsaws that I use the stuff in. The place where I get my saws serviced
strongly recommends only using ethanol free fuel in them, which by
definition, means premium gas. I've not heard of any ramifications from
using the stuff.

Holy Cow! I own some really good chainsaws - both are Stihls, and neither
will start on the first or second pull unless you've been using them for a

Doubt that greatly! There's no viable electric alternative out there today,
or even on the horizon, even for the consumer - unless you're talking about
sawing up a 1" branch two or three times a year.

Indeed - but using that ethanol crap will hurt yer pocketbook even more.
Ask me how I'd know - have you priced the newer fuel lines that are
impervious to ethanol? Of course you never really come to understand these
costs until that day you go out to use the machine and it's pouring fuel all
over itself through the deteriorated lines. It's almost highway robbery!
Don't even get me going on trying to rebuild carbs on small tools like

I have a flex fuel and I refuse to use the E-85 stuff. Sure, it won't
do any damage to my vehicle but why would I want to get 30% less millage
and pay almost the same price as gas?
It pisses me off that the corn ethanol is mandated by the government to
subsidize their failed corn farmer policies. We're paying for it with
our tax dollars, yet it still costs almost as much as regular gasoline.
So why the #U@& would I pay as much for it as gas and get 30% lower
millage. If I'm subsidizing it, it should be much cheaper.
Also, how the h3!! does it fluctuate perfectly in sync with gasoline
prices when it only contains 15% gas? When gas is 2 bucks a gallon,
E-85 is around 2 bucks. When gas is 4 bucks a gallon, E-85 is around 4
bucks when there's no fluctuation in the ethanol supply and the price is
controlled. Who's doing that math? What a rip-off.

Electric chainsaws have definitelty been around for a while now, but my
point was the real usefulness of these saws - not the availability of them.
As I said - unless you're looking to cut up a small limb a coupld of times a
year, they are not practical.
I live in a log home, so I own an electric chainsaw (not one of my Stihls) -
saves on the fumes, etc. (When you remodel; a log home, a chainsaw is your
tool of choice). That kind of use though is not what 99% of people think
about when they thinki about chainsaw use.

Ahhh-So... That makes more sense. Pulling it over those couple of times on
full choke is the same thing as if you had the ignition on. More like the
way my saws behave. Stone cold, my big saw usually takes 3 or 4 pulls on
full choke before it coughs, then starts on one or two more pulls with the
choke set back to half. The little saw generally starts with about the same
amount of pulls - maybe a pull less.
As an aside, the saw I had prior to buying my 361 was an 034AV (Stihl). I
owned it for twenty years or more and it was a great saw - never let me
down. But - all of its life it was a cold blooded saw - right from day one.
Seemed to pull it forever to get it started cold. Carb was adjusted
correctly, good spark plug, etc - but.. it got you warmed up for a day of
firewood just in the process of starting it. One day it would not start. I
knew that could be fixed, but I used it as my excuse to buy a new saw.
Bought my 361 and had the guys at the shop go through the 034, which my son
took posession of when they were done. If I remember correctly, they put a
carb on it - or maybe they rebuilt the carb, not sure. Once my son got it,
that thing started like it never had before - sometimes easier than my new
saw. Still running strong for him now, and he puts up about the same amount
of firewood as I do every year.

I don't doubt that, but it's more of a one-off story. You couldn't use that

No doubt, but that class of saw is not intended to do the work of a gasoline
powered saw, which is the only comment I was trying to make in response to
John's comment.

Sorry, but I'm really not familair with either the Remington or the Partner.
What I will say is that no 40v saw will keep up with my Stihl 361 out in the
woods for the day of puttin up firewood. Show me one that will drive a 25"
bar, and cut all day long, as fast as mine will hog through a 36" maple.
Going back to what my original point was - I was responding to John's claim
that the gasoline saw was on its way out in deference to electric models. I
simply disagree with this asseriton and think it only comes from a guy that
does not use a chainsaw.

Turn of a phrase, and a matter of perspective I guess. I would consider
most of what you do in your yard to be small work a couple of times a year,
compared to putting up a season's worth of firewood. Remember - I do own an
electric chainsaw as well as my two gas saws, so I do appreciate what it can
do. With that said - it would in no way keep up with even the small gas saw
in cutting through something like a 10" limb.

How big of a bar will your 271 take? I've got a 25" bar on my 361 and the
Stihl dealer said that's the longest bar he would recommend for it, and
still use a full chain. It just hogs through wood so it's clear the saw can
handle that much bar. Don't know what your 271 could handle but it may be
that you can get into a bar long enough the drop those trees with two cuts.
I've had to do that in the past with big trees that my bar couldn't just eat
through. It would be both cheaper and a lot easier on the back to manage
that 271 with a longer bar, than to step up to a 461. The other
consideration is to put on a longer bar (one that is longer than recommended
for your saw), and go to a skip chain. It won't hog as fast as a full
chain, but is still a serviceable tool - especially if you don't have
continued use for a big saw like the 461. I should think - without looking
it up, that your 271 would take a 20" bar, which would then be enough to
drop and block your big trees, albeit with two cuts.

It is the old term, "what the market will bear". Same goes for the
industry as a whole.
Ten years ago gasoline was at record highs. Prices were sold as supply
and demand. There was no shortage, just a lack of competition.
So again, "what the market would bear".
In recent years there has been more competition and even more supply and
up until relatively recently the much lower prices at the pump was
profitable for all producers. Supply and demand could finally be the
reason for prices.
NOW there is a huge supply with basically the same demand. More
competition has ultimately driven prices down at the pumps, not the fact
that there is more supply.
BUT some HUGE producers are continuing to over produce, and at a loss,
to drive the smaller competitors out of business. Then there will be
less competition and prices will absolutely go back up to "what the
market will bear".
There is a reason the Shell, Chevron, Exxon, Phillips, Conoco, Texaco,
and "name your major brand" have joined forces, to eliminate half the
competition.

Tell my Remington saw that. Theoretical is something north of 12:
effective is something around 10.
It'l rip your arm off if it doesn't start.
My old Partner, on the other hand is around 9:1 theoretical and
5.something effective. The little remington has more OOMPF than the
big partner. The partner would likely run on kerosene if you could get
it lit - the remington will overheat on regular gas, but runs great on
high-test.
Makes a difference what oil you are running as well - and how much.

Doesn't need ether - it USUALLY starts on the first or second pull.

I tend to use 40:1 instead of 50:1 so it does smoke - but it is close
to 50 years old and has never been apart. And other than the extreme
high compression kickback, it is NOT hard to start. I run ethanol free
premium, and even after sitting for 2 years with a full (sealed) tank,
it started on the second pull.

If 93 octane drops to 87, think where 87 goes!!!! The more oil, the
lower the octane - one advantage of the lighter mixes.

It's readily available, though expensive, here in Georgia. It doesn't

Using higher octane than required won't hurt anything except your
wallet.

Same many places here. The "regular" gas is 87 minimum octane - may be
slightly higher with up to 10% hooch. The premium is a "tier 3"
gasoline of 91 octane and in the case of Shell (and some others) no
hooch.
Mid-Grade is a mixer pump, blending the hooch-poluted regular with the
high end premium - which yields up to 5% hooch and 89 octane.

I took down a complete cherry tree except for the bottom 4 feet of
trunk with a 10 inch electric on a pole. Line powered - not battery -
in less ths 3 hours. The tree was higher than my 2 story house. I
used the electric pole saw because there was no way I was taking the
remington up into the tree. I limbed it from a 12 foot stepladder with
the pole saw completely extended.
After I had it down to the 4 or 5 foot stump I pulled out the
remington, the noticed there was a tree service truck just finishing
up down the street so I asked them how much to finish the stump and
chew up all the branches so I didn't need to haul it to the dump.
Less than an hour later there was nothing left but some leaves and
twigs. (and the stump chunks I had other plans for)

fact that that wouldn't be legal or smart in many
jurisdictions (that's 100LL, and I'll allow you
to research what the "LL" stands for, and the restrictions
on the use of 100LL nationwide, or the efforts to phase it out).

Exactly! Typically alcohol reduces gas mileage. My Tundra which was
designed to run or regular gets better gas mileage with premium from the
same gasoline station. Now that the price difference out weighs the gas
mileage benefits I have cut back from using premium and over all my gas
mileage has suffered.
Now there are other reasons that I get better gas mileage from premium
but most likely the lack of alcohol is just one of them.

Should not matter at all, Premium over regular is simply more of an
additive to increase octane to help prevent engine knock.
Vehicles have knock sensors that listen for knock and will retard the
ignition timing to help prevent engine knock with cheaper grades of
fuel. Premium fuel typically helps to prevent knock and the ignition
timing will electronically advance for better power and gas mileage.
In the old days when you set the ignition timing manually the engines
would truly run hotter if you advanced the timing too much.
Relatively modern engines these days monitor all of the engine functions
and make adjustments accordingly.
If you chain saw has an electronic ignition and a knock sensor the
timing could be advancing with premium fuel and running hotter. Or you
could simply be getting a more complete burn with the better fuel and
naturally running a bit hotter.

In keeping with the theme I mentioned the other day about not wanting to
accumulate stuff any more, I don't visit Craiglist as often as I did in the
past... I used to look at it a couple times per day to see what tools,
bicycles and furniture were there. I stopped doing that unless I'm looking
for something specific... This as the problem with deals is you buy stuff!
In hindsight I feel blessed that I've sold more stuff on CraigsList than
I've bought there. ;~)

May I be the first to say that "You Suck!"? <g>
Funny how things work out, eh? I marvel at all the deals out there on
Craigslist. If you are patient or knowledgeable or just plain lucky you
can score just about whatever you want or need at a great price.
I use a program that will search for items I'm looking for in a given
geographic area and "report back to me."
Son in law was setting up a new dental practice and our daughter scored
a like new set of reception room furniture (about 12 chairs plus tables,
etc) from another dentist who decided to redecorate after two years.
The cost? Gasoline needed to make two 60 mile round trips to pick them
up as they were free.
Gotta love it.

Yep, goes without saying. Early bird gets the worm, but you need to
know where the worm is. My latest "You Suck!" was a vintage Stickley
end table that retailed in the early '60's for ~ $1,200. My cost was a
couple of calls, a 50 mile drive and $45.

Perhaps two HF saws? I saw a video from the UK where there was an Alaskan

might suffice perhaps!
The whole rig looked crazy to me...

As fate would have it, to help with my decision making I priced the Stihl
MS461 at the shop where I got my MS271. Last evening I happened to look at
Craig's List and a new listing showed up for a "like new" MS461 in a town
about 35-40 miles away. It turned out the guy bought it at the end of 2014
and then promptly split up with his wife and moved into an apartment. As
such he no longer needed the saw to cut large trees for firewood to heat the
house (which the wife got). He also happened to be coming to my town
today... With that, without leaving the house I got an MS461 with less than
two tanks of gas through it, plus 2 new-in-the-box chains, for over a 1/3
less than the local shop's quote. Other than some wood chips on the chain
the saw looks brand new...
Worst case I can probably cut the two big problem trees and then sell the
thing without it costing me anything... or I can set it up with an Alaskan
Saw Mill kit and still be into it for a couple hundred less than the price I
was quoted for the new saw alone. Funny how that worked out... Merry
Christmas to me!

I haven't ruled that out completely but I've had such poor experiences with
other large tool rentals that I'm reluctant to do so--the stuff had been
abused and suffered from a lack of maintenance.
Another issue is that I haven't found a local rental business that rents big
chain saws... most have saws the same size or smaller than what I own.
I hadn't mentioned it here previously but it occurred to me that if I got a
big chain saw I could also use it for an Alaskan Chainsaw Mill. I figure
that if I can reduce a log into pieces I can handle I can finish sawing it
on my 36" Crescent bandsaw. I think an MS 461 would fill that role pretty
well... The two big trees would be the first ones to go as they appear to be
sound. There are a bunch of other large ash available on neighboring
properties that I'm sure I could get for the asking as the Emerald Ash
Borers have attacked them too. Being in an area not accessible to a bandsaw
mill those trees would otherwise end up as firewood.

>Oh just admit it John - you just want to have the biggest chainsaw on the

A bit of New Year philosophy:
Oddly, there are a lot of things I don't want to own even if I could or
do... In the past few years I've sold, given away, and thrown away a lot of
stuff. I can walk through my basement and shop now without having to
"navigate" and the things I actually want to use can be easily reached.
Getting rid of about 12 barrels of small pieces of wood and using pieces
that had been sitting there for 10-20 years for some undefined 'special
project' helped a lot... What was I thinking! It became abundantly clear
while cleaning out and organizing the shop that I don't need any more
woodworking tools... outside of a few larger mortising chisels perhaps. I
think my long distance self-supported bicycle trips (about 7,000 miles) and
working at Colonial Williamsburg, VA have made it very clear to me that you
don't need a lot to do a lot!
In the case of those two large problematic trees I'm afraid that site
conditions and the natural lean of the trees present problems. The cutting
plan is complex for the ash as I need to fall it away from the natural lean
and it is very close to a structure... so close that part of the back cut
will need to be made from the notch and back with a short bar or I'd need a
long bar (36"+) to plunge cut it completely from one side to establish the
hinge. Things will start by removing half the branches to shift the center
of gravity...
In response to the other comments on how I might use the MS271, there is
information on YouTube on how to cut trees up to 2 1/2 times the bar length
in diameter. In the case of the ash, the Game of Logging training I took
combined with this technique makes this look viable to me with my MS271.
https://www.youtube.com/watch?v=Iqp4d_-otHQ
What tempers this is that I'd like to mill the ash into boards. However, it
would need to be done in its current location. Getting a band saw mill to it
or getting the logs out of there are both not viable options. Here is where
having an MS461 and an Alaskan mill kit would be nice.

Mabee in the US of A, but not here in Canada. Ethanol is used as an
oxygenator up here. The extra octane is just a "bonus" if you can call
anything that reduces the energy output of a fuel a "bonus"
Up here it is "may contain up to 10% ethanol by volume"

Those things are sensitive, and with no carb adjustment available
they run just enough too lean on Hooch that they hardly run at all..
