OTOH, when the points are closed, they have very nearly zero resistance,
while the Pertronix still has measurable forward voltage drop, meaning the
coil doesn't charge quite as high.
And even with points, the rise time is very fast compared to engine
rotation. I doubt you'd see the difference on a scope.
Even if it does make a difference, is more spark advance necessarily a Good
Thing? Might lead to preignition at high revs, definitely a Bad Thing in my
book <G>
This wasn't caused by too much advance, but I think helps demonstrate the
point
