i would call the crank for the peddles cranks ,,with a "s" and drive-shafts are on cars ,,
i wounder if my crankshaft is bent or that taper is wore out
because i am wearing out the bushing very fast less then 100 miles or i break the spring fist ...
john i never use the wider cranks i just order shorter ones
6 1/2 in. works out well and very strong and the choke works out fine
HoughMade thanks for that
