Probably can't see it very well unless you bring the pic up to full size but the piston looks good looking in the exhaust port and the compression is really nice even compared to my other SEZ which runs great. These things are a pain to get the flywheel off sometimes, I'm going to make myself a remover that is like the Stihl 044 flywheel remover today to help get this one off.lets hope she was running rich enough to survive that chain.
It's funny you mentioned that, Me and my son went hunting a couple of years ago and one of the guys in our camp had a saw that was so dull that it blued the bar, rolled an edge on the bar and then spread the bar where he had his chain so tight at the beginning but the chain would just stretch and there was no tightening it up. When he started cutting he did the handsaw action and I just looked at my son and we both started laughing. I walked over and told him, hey it's a chainsaw not a handsaw going back and forth isn't going to help it.I laugh at people trying to cut with dull chains the start doing the hand saw motion back and forth thinking it helps........lol
