Actually I was thinking about using a sin= gle=20 cylinder motor cycle type of magneto directly on the crank for the trailin= g=20 plugs. At first I was going to use a snow mobile type (I have a few laying= =20 around) but then I realized you couldn't use waste spark on the trail= ing=20 plugs &#%*$!

I would just add another coil and ignitio= n pick=20 up to the motorcycle unit 180 deg out of phase. If I was really ambitious=20= I=20 could even add a couple lighting coils and have a (weak) back up to t= he=20 belt driven alternator. Probably I am not that ambitious since t= he=20 battery gives you some reserve if an alternator fails. If the battery fail= s=20 you are sol either way...but the engine keeps running.

reasons for the motorcycle mag:

1) cheap

2) no distribution problems, each plug ha= s it's=20 own coil and wire.

3.) no high altitude arcing.

4.) cheap

For fuel, I was thinking about using a ki= nsler=20 style fuel injection. Should be relatively easy with the rotarys linear po= wer=20 curve. No falling off on the top end means you don't need a high speed byp= ass=20 circuit. Should be able to control the mixture with the barrel valve. Of=20 course it will not be as precise or automatic as EFI. Should be just as go= od=20 in cruise once you get everything dialed in which is where it counts=20 anyway. The big benefit is I could disconnect the battery and the eng= ine=20 would loose some rpm, but it would keep running.

Proper shut down procedure (using th= e fuel=20 shutoff) should prevent the chance of firing when switching on the ignitio= n=20 (still should yell clear before touching the switch, if it jumps pilot mus= t=20 wear a hair shirt for a week for failure to follow shutdown=20 procedure)

Motor arrives tomorrow.

A friend had that on a Can Am Lola. It had a 5 position valve in the re= turn=20 line with 5 different pills to select from for tuning. It worked just fine.=20= The=20 electric pump was used until the engine started, and then was shut off. That= =20 would be your back up in case the engine driven pump

were to fail. I would make one of those positions a return through a bi= g=20 needle valve, like a model airplane. So you could tune right to a particular= =20 EGT.
