I would think it would work with yours doesn't it have a piece like this. the cast one not the billet oneThis a great project and I'm following it closely. I'm wondering if that engine and the adapter in the link you posted would work on a CC2166 that has a 16 hp single cyl. Kohler Command.... also will you have to modify the drive shaft length to allow crank side with pto clutch to line up with the mule drive?
Please keep us posted on this project along with pictures if possible.
