Re: 1957 Fleetwin 7.5

Would love to see a picture of the upper spark plug gap that was fused together…This concerns me. Was the engine seized when you got it? It kind of sounds like water may have been present in the upper cylinder, you will want to investigate this further. You will need to pull the powerhead to replace the impeller, have a close look at the lower crankcase seal….The lower seal is made up of several crazy looking pieces that must be properly assembled or the powerhead will ingest water and slowly be destroyed.
Like others have said, I would pull the flywheel and have a look, or at least pull the inspection cover on top of the flywheel to see if the coils are any good. Drain the gear lube looking for the presence of water. These are nice engines but you don’t want to invest a lot of money until you confirm the powerhead/gearcase is in good shape.
Those plastic emblems are tough to find, and usually command big money when you do find them. I know there is at least one club member who might have one….Can’t remember his name right now, but think he goes by "big Steve"….
Again, post some pictures so we can help you evaluate this engine.
