    ct90 and atc 90?

    I'm wondering, are the parts from these interchangable?
    My neighbor has a ct that needs an ignition coil and i have a coil off of a 90 that might work. the engines look almost identical except the ct has a kickstart.

    They should interchange. If you really want to go crazy, SL and CL 90 parts interchange also. That could give you an atc90 with kickstart, manual clutch and no hi/lo gearbox. Food for thought.
