Hillbilly: What are you planning to do regarding timing adjustment?
Late reply, was on holiday in Scotland...
Gear on magneto is not keyed, so move around to get timing right before tightening locknut. Finer adjustments possible later on as well since the magneto adaptor plate can be rotated by a few degrees.
About the factory drg of the Pan/Knuckle magneto drive... Got mine on Milwaukee Belle/Eric's web Beauty of Speed... But who's had it 1st up
