Could we just run a 12v CDI module in loss mode? Power it from a rechargeable battery. I was reading the post on the Walbro carburetor, and ended up on an RC airplane engine page here. They run their engines without an alternator or magneto, just use a NiCad and have no problems.

This way you could use the pulse wire from the engine and a hi output CDI.

Then you can get into crazy stuff like using the Shimano hub generator and a voltage booster to kick the 6v upto 12 volts using a voltage booster.

But, take all of this with a grain of salt, I am still mounting my engine, so this kind of performance mod is waaaayy down on my list.
