Hi Tom,

You might want to make sure the coil is in tune.  I got racing sparks on my
3.5 inch coil when I went from a 6k/30 to 12k/30 and had to hafve the
capacitance.  I ran out of primary turns to compensate and got racing
sparks.  Added more copper and retuned the coil and racing sparks
disappeared.  I have heard that out of tuned coils can cause this, but I
don't think I can explain why.  Maybe someone else can.
