another problem with the kit you're looking at is the spark plug that is needed and included with the kit, it has 10mm threads, and your engine most likely has 14mm threads. if you have a metal lathe or access to one, there's a simple solution involving a discarded car spark plug (I used one from a chevy 350), part off all but 3 threads, drill out the center to the size needed to tap the hole, tap the hole in the middle, then part off the rest of the plug just past the sealing taper and face it so the new plug will seal. or you can just buy the adapter from CH or get an ignition module that takes the right size plug...
