I have a Poulan 2150 that will not start. It runs for about ten seconds after I prime it but after that it won't restart. Tried several times. Only runs on the primer gas when I push the bubble.

What are the settings for the hi and low needle valves. Also where do I set the idle screw?

I have installed new carburetor kit with intake gasket. New fuel and air filter. I have done about everything I can.

Any help appreciated.

Hi,
It still sounds to be in the carb. Sounds as if it is burning the content of the metering side of the carb and then getting nothing. Sounds as if it is not pumping to refill the metering side.

Is it possible there is a fine crack in a fuel line that would do that? I sure can't see anything or any leakage.

Hi,
Yes Poulan machines have cheap fuel lines. Find some Tygon or the like and replace them.
Peace,
