Yeah I've done everything I know how. I rebuild the mcculloch chainsaws as a hobby and I have 4. So I know that the engine is a modified chainsaw. I have that going for me. The carb is a glorified lawn mower carb. When I got the carb in, I took it all apart to see about cleaning and it was perfectly clean. The drain on bottom does its job and I have fuel coming out. (Waiting on a carb kit for it since the drain gasket is bad and causing a leak.). I have tried every throttle position, spraying fuel past the reeds,spraying fuel into cylinder and reinstalling spark plug. My points gap is a .20 and the key is not sheared. My compression is 92. I'm just baffled to what could be going on.
Bringing them back with a little TLC.
