I just acquired this machine for some summer tinkering. After getting it home, I realized it was missing several vital components, such as the engine cases, carbs, two pistons, a cylinder, among a bevvy of other parts. The PO had dis-assembled it due to a roached crankshaft. Is there an online resource, besides Ebay and Greenhulk (which are both inaccesible from my work computer, which is where I do most of my searching) for used parts?
