Chainsaw Repair

the 562 I'm cutting with is the first 562 I ever got and the piston is cut to hell in it .080 above ring land , side ports inlarged a ton and motor screams hard all day long and no problems of any kind , in this heat it runs alot better than the carb saws, I have not seen or ever heard of a piston problem up here nor has Red ever said anything of a problem as he has sold a ton of 562's , biggest problem is the carb setup but once you figure out how to make them run proper that is not a problem either . I NEVER use the decompressure of any 562 or 365/372xt ever
