Bought one last year for $20. About same condition. Runs pretty good, sounds freaking awesome. Have not cut anything with it yet.
I have one of them in the shed as well. It was given to me by a friend, it was originally his fathers saw.
One of their factory hot rods,very close to a full on racing kart engine.5.3 cube/87cc produced from 1968-69 (the one in CL listing with slightly different label on air filter cover,couple other features) & mine shown here from 1970-75. Will pull 36" bar/full comp chain in hardwoods no problem,42" if skip tooth.I've since added large 4 tooth spike
