I have a 1954 Fleetwin 7.5 that i recieved for free and currently trying to get it back to working order after it sat for several years. It runs but seems to pull water into the cylinder. I was curious if there is a seal that might be bad.<br /><br />If it helps when I recieved the engine it worked fine but the coils were shot so im pretty sure it's not a crack or anything.
