I guess I ruined my OS by running it to lean, the piston top is very
black, I noticed more black residue on the exhaust header and compression
seems to be very low. I am selling it for $40 US or reasonable offer or if
any one has had experience rebuilding such a model I would appreciate the
When I turn the main shaft counter clockwise compression is very poor but
when I turn the crank the way it fires clockwise compression is better but
not like I remember it. Hate to spend $119 for a new one.
Please share your thoughts.
