I bought a foot of special key stock for a future project and I'm taking a couple of inches of it to Bill this Saturday at Donut Derelicts. It's 3/16'' X 1/4'' and should fit into his crankshaft, taper adapter and flywheel. Once the flywheel is on he'll be closer to mounting the coil module and getting some spark. Then you know what happens. A little prime with or without carb and you can hear the engine pop. That would be huge progress and incentive to get it running.
