hi jim
        hows things ? the prob could be phasing of the rotary allowing the
voltage to climb and surge but most probarbly its because i suspect your
static gap ran at a lot higher bps than the rotary so now you get things
like inductive kick
also if you run 120bps then the resonant rise can be big causing a large
voltage rise
cheers
