bobdd,

Jerry Howell sells a TIM 6 electronic ignition kit for about $41. This includes the circuit components, Hall sensor, and Model Electics coil. You will have to provide some misc. wire, a plug wire/boot, and 6v. battery. I used a shielded 14mm wire/boot from CH Ignitions. The whole package weighs 3.25oz and works fine. Since it is a fixed timing unit, I set mine at 25 BTDC and seems to run well.

You could do a search on here and come up with the address.

Good luck.
Doug
