Are you using a flat primary? I had that kind of problem and then I built a
flat primary.

If your primary is flat, you might try covering it with a plastic disk to
try to reduce the strikage. Its doubtful it would help, but can't hurt I
suppose.

What are the dimensions of your secondary?

Better to attract the sparks to a spark ring than have that kind of voltage
going to the primary to dig a shortcut through the cap.
