Saw ran and compression felt good when I bought it. I know the guy I bought it from didn’t know it needed a piston so I’m in it for $60 and not going to go back to him about it. Exhaust side of the piston is scored and it was sucking sawdust. I just want out of it what I paid before I try to part it out. Lost the muffler since the first posting. $60 plus shipping. Prefer usps money order. Figure 15 pounds from 19567 to estimate shipping. Local pick up is also fine.
