Bought this saw a while ago. Planned on fixing her up but it just never happened. I HAVE NOT GONE THREW THIS SAW AT ALL. It was bought and has been sitting on my garage floor. Here is what I do know. Piston is scored looking threw the exhaust port. Saw left a nice puddle of bar oil on my garage floor and it appears to only be missing the flathead nut that holds on the cylinder cover. However it does appear it will clean up well and make a decent saw once all the issues are sorted out. $100 plus the ride.
