It appears your toroid is simply too large for your system.  A smaller
toroid will reduce the output potential slightly, however, a smaller toroid
often provides better spark discharges because the breakout potential is
smaller.  Your choice here is to use the "bump" or reduce toroid size and
retune for some nice dancing sparks off the smaller top load.
