Don't buy from Campbell Nelson they will rip you off.  I bought an engine
from them about 1 1/2 years ago.  The supposidely NEW engine was damaged in
about two dozen spots and the crate it was in was too small for the engine.
The top of the crate was cardboard!  Parts of the engine were sticking out
of the crate and hit other things.  I strongly recommend that list members
not even consider these guys.
