This is a complete running saw, I bought it a few years ago and cut a couple cords of firewood with it. Recently I decided to get it off the shelf and look it over, I pulled the muffler and it has a carbon streak down the exhaust side of the piston. Saw also has a hairline crack in the case below the flywheel. I have no desire to fix it, asking $300 plus shipping PHO. PM me with any questions.
