As far as I know and what I have been told, this more then likely hasn't run in about 20+ years. All the rubber parts are hard and brittle. The motor did turn over and wasn't locked up.
Did a leak down test on the cylinders and goes right on by. So it will get rebuilt and last another 50 years. As for the tranny, it is more then likely in good shape.
Unknown how may miles or hours are on it or how well it was taken care of, so to be on the safe side start with a fresh motor and paint job!
fun little project!
