Vince here is a project for you.
Two hand wound coils and two magnets.
Rotate the magnets in a device mounted 180 out on the e-shaft
nose and feed the hand wound coil voltage into any standard
Ignition coil and see if it will spark when the magnet goes by.
I found a couple of large 1 by 2 by 1/4 thick bar magnets and some
coil wire in radio shack.

This idea does away with the need for an ignition timing trigger,
alternator, battery and electronics as long as you use
gravity flow carbs. You might have to try several hand wound
coils until you get something that works. My guess is they
should develop 300 volts peak.

I have my plate full building this 555 EFI.
