I pulled the engine on my WC this past weekend. When I dropped the pan I noticed some rust on the crankshaft and rods. My plan is to rebuild the engine, which has not run in 30+ years. Should I attempt to remove the rust or do machine shops normally do this when grinding/checking the crank?
Also, I noticed a crack in the clutch housing. It is not all the way open, but looks like a hairline type crack that runs from the top down a ways. Is this a serious problem? Thanks for any advice!
