Two Spark Gaps In Series?

[russwr]

Great! Now one more thing,- It just seems to me, that If the positive high volts fires first gap as wide, and 2nd gap to ground is narrow, and in series, doesn't the final spark gap fire at same high voltage as first? The first gap has to fire to GET to the second gap to ground, and both points (gaps) are electrically connected together? In other words, final gap has to be smaller, but with higher voltage as fired. Of course a CDI unit can fire spark plug with higher voltage at plug with narrow gap, but that is always in microseconds, not regular needed milliseconds.

 Given two gaps in series both gaps would have to fire simultaneously. Say the narrow gap fired first; where would the electrons come from?

What do you mean by not regular needed milliseconds?

I built  a CDI for a chainsaw. At 1800 rpm it worked fine, at 3600 rpm it would blow the 10 ampere fuse in the 12v to 350v up-converter. I solved the problem by buying a new chainsaw 😉
