Yes, advise Ken immediately that you are going with electronic ignition. It makes a big difference in the type of prop hub used. With electronic ignition, you do not use the magneto flywheel at all. It comes off and gets thrown away in favor of a prop hub configured for electronic ignition.

The prop hubs for electronic ignition incorporate an internal taper to mate with the crankshaft, and are a bit difficult to manufacture. If Ken can't or doesn't want to do it, check back with me. I think I have one here, and some engine mounting brackets too.
