That was a starter/generator. Golf carts use them also. Mine has the pulley attached to the torque converter, that might be easier than putting a pulley on the flywheel, and keeps the rope start.That’s a great idea and it brings to mind the older lawn tractors (and other equipment) that used a belt driven alternator/generator that ran off a pulley mounted to the flywheel. Problem is, those may have been electric start only
