Which O.S. engine is this???
Crash & Burn, Hobby Services said that the bearings were "rough"? Did you look at them before starting it up? I think I would, just to be sure that I didn't tear up a really great engine. Bearing replacement isn't that hard and even if Hobby Services doesn't have bearings for it, I bet Boca Bearings does. (and at a better price to boot). Bearings can rust in an engine even if it hasn't been run, especially in an older engine. Take a look, just to be sure.
