Good, bad or whatever, my "Auction Site" motor arrived today. It's an A&M 3.2 with the A&M rod. Crank appears to be a Sachs. At some point someone used castor oil to run or store the engine with. It was gummed up pretty bad. I may have to install new bearings. Some how the piston got scratched on both sides and pinched the rings in the groove. Got them out but one broke. Even with one ring and everything cleaned and lubed it has really good compression. I'll have to pick up new rings and base gasket to try it out. The timing ring was changed to fixed type as well (monkey bracket to hold it in place). After new rings and gasket I'll put one of Ralph's ignitions (have two here on the bench) on it and give a good run on the test bench. Anyone have any favorite brand of rings to use? I know Frank Bowman makes good ones.
