Hi, got a 73 Terra Jet without the motor. Plans were to put a Honda clone 420cc horizontal 1" keyed shaft into it.
Problem:
the secondary clutch accommodates a 2" belt (like a snowmobile).


I'm trying to locate a primary clutch that will work with the larger belt and will activate at lower rpms than the original Kohler motor. max rpms are 3600 rpms


Seems all the clutches are for 1" or less belts


here's the motor specs https://www.princessauto.com/en/deta...rt/A-p8449019e


Any ideas or leads would be appreciated.
