FBO's black HEI ignition box

Fishmen,
I re-read your post #96 about the 'best spark' & I assume you mean a smaller plug gap works better in a 2 stroke.
There is a very good reason for that, which is unique to the 2 stroke. Two stroke engines are notorious for oiling up spark plugs, nature of the beast. One of the 'cures' is CD ign. CD ign has a very high energy spark, but very short duration, about 1/10 th that of inductive ign. This duration is so short there is literally not enough time for the deposits to bleed off all the spark energy. There is some energy left to fire the gap, but the gap probably has to be smaller because of the energy already lost. I'll bet if a more powerful ign system was available, a larger gap could be used & more power made.
David Vizard has talked about an ign system developed for F1 that sounded like a lightening bolt. It was so powerful that it was banned because it was feared a shock from it could be fatal.
