Electronic ignition

Does anyone know where I can find a schematic for the circuit board for the CH type ignition? (I believe that’s the right type ignition.)

Try this:

Thanks I’ll see what I can do with that. My lawn guy just gave me about 6 weed eaters, a chain saw, and a gas powered hedge trimmer. So I got all of these gas engines to play with, plus A friend just crashed one of his planes and though it demolished the fuselage the wing was unscratched. It’s a 72 inch wing so I’m thinking really nice plane.

Check this site. I think he offers ignition kits.
