Yep already done tore it down. Other then what I can only say must of bein caused by overheating and a good size chunk of carbon sticking just right of the exhaust port and then eating away the piston the whole saw is very clean and all original. Both spark arrestor screens were still in the factory duel port muffler which means it a 066 magnum red light. I'm wondering whats the best top end to toss on it. I want a bb with popup and the hyway
Wouldn't by any chance have a good used piston and cylinder for one would u?
