Cub engine power unit.

FIL want to take his engine out of he cub to overhaul engine since it smokes. We got a cub power unit and would like to put it in for now until the engine gets built. I want to know on the power units are the governor differnt on theses then the tractor. I know some combines runs the opposite governor set to run wide open and adjust with throttle to idle down, so I didnt know if it was the same or not? THanks for any info.
 
My only experience with a Cub power unit was the one Dad removed from a 50-T baler. The governor worked the same on that one as the one on the Cub tractor...except it allowed about 400 more rpm.

If you"re gonna use the power unit in a Cub, and you don"t have a particular use for the gas tank, rear tank mount, hood, and grille from the power unit, send me an email...I"ve got a project working that needs those items.
 
Not if it's a Cub engine, like he said it was. Cub used an IH-built C-60, which had the carb and manifold on the left and the starter and mag/distributor on the right.
 
My Cub power unit from a combine has what I think is a steel crankshaft, probably to take the increased RPM. Darald
 
We had a Cub engine on a combine years ago and it ran up to about 2000 RPM and it definitely had a lot more power than a standard Cub engine, if it runs well I would consider leaving it in the tractor. You don't have to run higher RPM's but they are there if you need them. But if you need to put that engine back as a power unit, then different story.
