The way it was geared, it was no wonder. It had a gear reduction PTO to jackshaft, plus at jackshaft to rear sprocket! Check out the drive system the PO came up with. I have to appreciate the ingenuity, but then wonder “why”? Instead of bolting on a centrifugal clutch, he made his own engine plate, flipped the rear wheel, and added a jackshaft. I guess so he could run the belt system, which is dangerous because you have to pull the lever or push the pedal to disengage it. Meaning, its normal condition is hooked-up and driving. Not safe IMHO. So, I’ve carefully dissected everything (see pic in post #7) and will be reconfiguring it to the standard layout. At least in terms of the drive system. Totally going to be a resto-mod, otherwise.
