That points towards straight gas being the culprit usually.

Clean the aluminum from the oem cylinder and stuff a new oem piston back in then pressure/vac test it, the value of a all oem saw vs aftermarket is easily double. I would not make a name for myself selling saws without disclosing aftermarket parts contained/listed there in.
If you buy aftermarket parts you better have the tools to check cylinder bore out of round and piston size. Yea you'll get lucky a few times without doing so but it will bite you eventually. If your not prepared to spend 10 hours tearing one down to clean/rebuild it you won't go very far buying old saws to make money, You will waste more time doing things over and over when a cleaning and full tear down from the get go on scored cylinders/pistons would have saved time/frustration and increase the value because its clean. Vac/pressure testing also needs to be employed.

Ah....thanks so much. Love the education! I'll still pressure test to make sure all the seals are good and check the manifold boot.(if that's what you call it)
