It's my own design, I have an AC transformer that steps 120VAC down to 12.6VAC
then I have this going into a relay that switches 9 volts into a 2n3055 power
transistor that switches <mailto:12V-at-4A>12V-at-4A into the ignition coil. I re-did
the primary with bare wire and made it 7 turns and added a soda can topload and
I get about 1 inch sparks now. I think I need more primary turns.

What circuit are you using to power the ignition coil?
