TES,

Yes, your understanding is correct about rotating the motor to make 
gaps fire at the correct point along the 60Hz AC sine wave.  Just 
adjust the phase for best spark output.

I'm not sure I understand what you are asking about the resonant
frequency.  I suppose you mean the RF tank and secondary 
resonant frequency, for example 250 kHz?   The sync-gap is not
affected by the RF resonant frequency...a particular sync-gap can
be used at any RF frequency without modification.  The gap does
not synchronize to the RF frequency...it can't either.
