I recently picked up a 056 Super crankcase with 54mm piston. The autopsy showed that the case met its demise when a small fragment of piston skirt broke off and pieces ended up in the bearings. The flywheel was attached and covered a mated pair flywheel and ignition module. After digging out the metal from the bearings, they spun freely but smoothness was questionable, and I decided it was not buildable without splitting. I would like to sell it or components, but the problem is I can't test the module. Since I'm pretty sure the module was working at the time the saw broke, it's very likely that it is good. I'm looking for someone who is building a 056 and would be interested in testing the unit with the option of buying it if it works. Because of parts swappers, I don't trust ebay buyers, and don't want to sell it as untested with no returns. If a fellow site member is interested, PM me and I can give you all the info and pictures you need. The crankcase and crankshaft are in excellent condition.
