Hi Al,

I can't find any reason why it does so well. Your basically saying that
your coil can produce up to
7 or 8 foot sparks with a tiny little screw as a top terminal. I can't find
any reason why it does
so well. But your sparklength based on watts is about where we would calc
it (7.4 feet). I have no
explanation why.

Take care,
Bart Anderson
