Aside from any differences in the PTO end of the crank, are the vertical and horizontal crankshafts interchangeable?
Trying to find a Model 19 flat head crank without the synchro balancer, seems that crankshafts out of horizontal engines are much more plentiful than vertical.
Because of our rules, I must use Briggs parts, so I can't just put on the ARC Brass weights.
