This is way off topic but maybe someone knows.. With a full tank of gas, my
lawnmower stops running after about 15 minutes. After it stops, I press the
primer button a couple of times and it starts back up. Then after a couple
of lines, it dies again. It does this repeatedly until I finish about 30
minutes later. I've already taken the carburetor off and cleaned with carb
cleaner. I cleaned the air filter. I cleaned the siphon tube. It does not
misfire or run rough in any way. It acts like it stops drawing gas. Any
help? BTW its a an MTD 4hp push mower about 5 years old.

An unkind remark is like a killing frost. No matter how much it warms
up later, the damage remains.
There is not a plastic cap under the gas cap that looks like it
belongs there Is there?
It is supossed to be thrown away when the mower is 1st. st up.

Check your Air Filter. If it is real dirty that will cause the same
problem.

Other than the other suggestions, I had something fall into the gas tank
once. It would run a while, then the object would block the gas line and
the engine would stop. After it stopped and sat a while, the object would
float away from the gas line and I could start it again. It would run for a
while until the object blocked the line again. And so on, and so on. It
took a while to figure it out. Also, if you have an air leak in the siphon
tube, it can do the same thing.

Tim,
We need the brand of engine on the mower and the engine model number.
Should be on the flywheel housing somewhere... Briggs engines are usually
on the top, Tecumseh on the side or a tag on a bolt. Honda is embossed in
the rear of the crankcase.

The air vent on your gas tank is blocked and it's developing a vacuum
in the tank. Try running it with the cap open and see if that helps.

I don't have a fuel filter. The carb has a pickup tube going straight down
into the gas tank. At the bottom of the tube is a screen. I already tried
cleaning out that screen. It did have some debris on it, but it didn't make
a difference in the cyclic running. My primer bulb is black rubber. I
can't see through it. Any ideas on how I can check if it has a pin hole in
it?

Soory LJ and GTO - my new Bolens 4.75 hp has a clear primer button, the same
as my old Murry and yes - my weedeater also has a clear (but somewhat
yellowed) primer bulb.
10:1 odds - huh? Hmmm - it's either that or an extremely dirty air filter.
Before you say it - I know - he said he cleaned the air filter. Sometimes
the cells in the foam crush and can no longer be cleaned. This will also
rob the engine as well. I wonder if he has tried taking off the fuel cap
and the air filter and see if it clears up? If so - then replace one at a
time and check for normalcy.

What brand engine have these mowers of yours had? I've had 12 mowers and worked
on maybe 20 more, all with black, white, or red primers. Briggs, Tecumseh, Lawn
Boy, Suzuki, etc. All opaque and air-filled.

I'm going to try removing the gas cap (or at least loosen it most of the
way) and then removing the air filter if the gas cap thing doesn't work.
I'll just have to be careful not the get grass or dirt into the carb
opening. I'll try this weekend so I don't have to waste gas just to try it
out.

Dont remove the gas cap;;;!!!! simply loosen it a turn or two. You dont
want gasoline splashing around on your yard or you may not have any more
grass to mow. Try just letting the mower set still and run for the allotted
time.
If that does not fix it, go and get a Honda. I bought my Honda in 1987, and
it has never been in the shop, has had 1 air filter and spark plug
replacement, still starts on the first pull even after setting up through
the winter, and the oil stays perfectly clean... 17 seasons and counting.

I'd probably advise against getting a new Honda these days. The engines are
great, but the rest of the mower (lots of user complaints with the drive
system) can be fragile and parts are very $$.
Toro, John Deer, Snapper, Lawn Boy, and Ariens are in the same range as Honda,
with more happy owners. Actually, I might not put LB up there any more. The
2-stroke engines are going to be dropped next year.
I have a Toro from 1987, Lawn Boys from 1965, 1973, 1986, and 1992, plus a
Flymo from the '70s all in good shape. No work needed other than some
age-related problems in the old LBs.

Huh? You're thinking "boat" fuel system, Jums.
Mower primer bulbs are almost all black/opaque
and the hole in the outside means that it would
never have gas in it.
Of course, you use pineywood, so I wouldn't put it
past you to mow the yard with a Merc 90 that had
string trimmer lines dangling from the pretty, shiny,
brass prop, KWIM,V?
P.S: 10:1 it's a clogged fuel cap vent.

The diaphragm has a hole in it... usually under about 3-4 screws on the
carb.

No, a clogged air filter would flood it so the primer wouldn't
be of any use. That's the opposite of what he has, Rog.

steve and roy may be correct; also check for a clogged fuel filter.
cars will run for a while and then stop or slow down when the fuel
pickup screen in the tank is clogged.

Also - check the primer bulb for a pin hole or a crack. When you prime it -
your finger may be covering the hole (if it's there.) When the engine is
running - you should see gas in that bulb at all times.
