This doesn't make sense. The faster you turn a mag, the hotter the spark. That is why there is an impulse so that you can get a hotter spark at hand cranking speeds. the impulse spins the mag faster under spring tension.

I am not challenging your statements, but this really just doesn't add up. If the spark is hot at impulse RPM's, it should stay hot, and get even hotter at higher RPM's, ie. running.

I need to noodle on this a bit. Although it could be the coil has a partial short in it, and it doesn't ground out until you are getting the higher voltage from the higher RPM's. the condenser may be playing a part here to. I have just never heard of this behavior before.
