Why does my Poulan 2055 saw stop after it starts?

SOURCE: Poulan 2055 will not start

I would recommend calling their tech line at 1-800-554-6723. But in my experience most 2 cycles don't really have valves that stick just slots cut into the cylinder to exhaust the gases. Let me know what happens please

If it is a old saw it sounds like your engine seals are failing. when a engine seal fails it allows air in past the crank upsetting your fuel mixture You could try to richin the fuel mixture by turning the screw marked H anticlockwise a quarter at a time untill it runs Ps to set (h) screw to factory, screw it in til it stops then unscrew it 1 & 1/2 turns

Two items you can check:

1. There is most likely a spark arrestor screen on the muffler. These can become clogged with carbon and choke out your saw. If it is removeable, usually by taking out a single screw on the screen, you can clean it with a wire brush.

2. Check the compression of your cylinder. It should have a minimum of 100#.

A couple of ideas, it could be a fuel tank breather issue, when it starts to die just try loosening the fuel cap, if the saw picks up again you will need to change the breather, the only other thing i can think of is a bad ignition that is breaking down when hot, the only aswer to this is to replace the ignition unit

Usually when a small engine starts fine.. runs fine.. gets hot it's ignition related.

First you want to make sure the cooling fins are clean.. remove any covers and clean the area around the head. If those fins are clogged.. not good.

Second I would check the spark.. and the spark plug condtion.

Also for power tools that don't get used that often.. fuel sytems get gummed up.. fuel gets old.. and folks tend to use the fuel in the can they mixed two seasons ago. Make sure the fuel mix is correct.

I assume it is running fine with the choke off.. however check the choke for proper operation.

Clean or replace the air filter as well.. once all the ignition and fuel components are in good order.. only then should you begin to adjust the carb. Probably not needed.. but don't do it until you are satisfied that you have good air fuel mix and proper spark.
Best of luck
