Buddy called me he has a 064 but it has issuses, piston is scored (top end), no spark could be as simple as a wire grounding out or off or it needs a new ignition, and it has no air filter. He said he wants 125.00 but if it has bottom end problems it wouldn't be worth putting that much in or would it? Top end piston cylinder bearings off ebay is around a 100$ air filter 25$ ignition 50$ so lets just say 200$ so I would have 325.00 in it without any other problems What do you guys think its a older saw just don't want a money pit saw that I put more in than its worth.
