Re: kinds of spark

I believe the key here is that your terminal is a "ball". I have seen
this effect in my coils when using spherical terminals, regardles of how
well tuned they are. I have also heard of other folks with spherical
terminals observing the same thing. A lack of wind or other airflow seems
to help, as well.
