This saw is just as I found it. Seems to have good compression even though the piston show some discoloration. I think it will run just as is if you assemble and find out what was wrong in the first place. Bearings and seals seem OK so maybe and easy carburetor fix. Low hour saw by the look of the components. &170 includes shipping. See what all the hype on the 550 is about. If it does not sell I will put it together in the future myself but have a lot of projects right now so willing to pass this along.
