And there it is..... Probably has the bigger housing on it. Not a Cub Cadet motor, so it didn't bolt right in.
The tractor should have handled 5' of snow and not broken the frame. It got weakened when you modified it. Not his fault.
Dale, a big flywheel 301 would fit in the 129 frame, but should have had the smaller one originally. Pretty sure they didn't go to all large flywheels in Cubs until the QL series, but seen some oddball stuff from the factor on the 1X8/9 tractors. Like factory black engines.
