Subject:  sync-gap problems

I've just completed an 1800 rpm sync-gap system. The rotor has 4
electrodes through its face and two stationary electrodes. The motor
can be rotated nearly 180degrees, also. 

My problem is no spark at the toroid. The rotary makes a dull thudding
noise when the gaps fire with or without any static gaps in series.
The static gaps also make this noise when used with the rotary.

When I remove the rotary from the circuit and use the static gaps, the
system works fine. This is the first rotary I have used so I don't
know much about them. I'll eventually figure it out, of course, but in
the meantime I'm open to suggestions.
