If you are meaning that the paint is to thick, you should try thinning
it. If you have the opportunity to change aircaps on your HVLP, you
should be using about a 2mm cap, not the stock which is usually
somewhere between 1.4 and 1.8 on factory equipped gun.
I have sprayed acrylic very well through my HVLP system with the paint
thinned just a little.
One not of caution; unlike many other finishes, the particulates in
acrylics must stay in suspension. If you over thin, you can ruin the
factory recipe and affect the wear/abrasion resistance of your
finish. Worse, over thinning can lead to a different color than you
want. A call to the tech line on the can will get you some guidance
on that.
That's one I learned the hard way.
On the other hand, that nift little Graco dx is only about $300, and
for that price it is a steal. It does some nice work without any
thinning of the paints. If you think you might paint the house, shop,
garage or anything else of size this is a great machine.

I think i have 1.4mm tip on the gun. I dont believe I can purchase a
larger tip for it. but I havnt tried thinning the paint. It is an acrylic
gloss (Olympic). Nothing on the olympic site but Ill experiment with some
thinning and see out it does. thanks

Have you considered using a paint conditioner such as Floetrol?
