[Bluecub]

I have a cub 106 with a k301 swapped into it, had to cut the frame little to get it to fit, let my buddy borrow it to plow his driveway and he returned it with a bent frame and a awful rod knock. Plan on completely rebuilding this engine but was wondering if it would be safe to put a smaller flywheel/shroud off of a k241 onto the k301 without having cooling issues or the crank being out of balance (as I've been told). Also, would the 106 "body" possibly bolt up to a uncut 129 frame? Any help is appreciated !
