Saw problems:
Mange, just out of curiosity, what was the comopression reading on the saw? Did you acutally take a compression reading or did it feel like it had good compression from pulling her over. I was thinking about a cacked, broken or missing ring or possible the wrong rings. Was the piston in right as Al had asked? To me, poor compression would lend itself to por impulse line pulsations and the carb running lean or not delivering it's fuel. Seems like all else was checked. Still don't know why the dealer wouldn't let you compare the new cylinder and piston against the old ones, unless he's already sent them back to the company for warrenty credit. Just my 2 cents worth for now, you take care. Lewis Brander.
