Public service announcement! The teeth on the OEM flywheel are really sharp. I was installing an old flywheel on my spare motor today. I need to bolt up my trans and starter to turn it over and see if I can get #3 exhaust valves to seat. The flywheel was a really tight fit on the crankshaft. It slipped and cut the crap out of my finger. I just ordered a set of gloves off Amazon
