I know Poulan are junk, but mine won't die after I switched oil. Little story for ya....Bought this Poulan, ran fine out of the box first year, second year they bastard wouldn't start unless you gave it a shot of ether. So one day I dumped the gas tank, got a quart of klotz 2 cycle oil to mix with the gas..now boys...klotz is for racing engines mind you. Started right up on first couple of pulls!!!! Been running that shit in it for over 2 years now and hasn't let me down, even tho, its a piece of shit...and....I like the smell of racing fuel
After I had a similar situation with my Craftsman (due to old gas I believe) I mixed in some red bottle HEAT. Worked like a charm. Thereafter, I always let it run dry with a HEAT mixture and poured the rest of the bottle in the gas can for winter storage. It always started easily the next spring. Cheaper than Stabil.
