Most modern chainsaws, string trimmers, leaf blowers and other small-engine two-stroke equipment recommend a 50:1 oil mix ratio, but some recommend 40:1 and older two-stroke equipment might even call for 32:1.

ANSWER : Yep they swell after a while and will not screw in or out!

Poulan pro 46cc will not idle
ANSWER : Fuel pump in carb is hard and not pumping. rebuild carb

My poulan pro 42cc starts normally, then as I begin cutting it boggs down and nearly stalls. As it warms up it seems to get worse, esp. if I turn it on the side to cut. I’ve cleaned it all up and checked the fuel lines. They are intact and no leaks or clogs detected. The only notable change is the primer bulb takes a little longer to return after pressing. It seems to idle fine and run good untill under work load.
Thanks for your help. Chas
ANSWER : Try cleaning your air filter. that should help. “BEEN THERE”
