I agree, i honestly think that the seller had no clue only because i could tell the saw had never been apart since new. I sent him a message about the issue. After cleaning everything up, the ring and piston look good as well as the cylinder. Im just thinking of putting it back together and running it. What do you guys think? Anyone ever been in a situation like this where the piston and ring seem to be still good after cleaned up.
Another thing i just noticed was that the paint on the inside of the crank case, on the flywheel side, is worn off. Ive never seen it that happen before. The crank is tight and the con-rod is good too.
Would you mind posting a photo of the cleaned-up piston? I have a Jonsered 920 with similar damage, probably worse than your 5100 though.
