RE>Magnifyer Coil Question (rotary)

synchronous gap firings occur at same places in all cycles (phase lock)

nonsynchronous gap firings occur at different (random-walking) places in all cycles

On a synchronous gap, the electrodes are aligned properly to fire
when the transformer is at a certain part of the 60hz cycle.  It keeps 
the voltages from charging up to much in the cap.  I'm sure someone else
can give you a much more detailed explanation though :-)
