To answer your last question, the operation sounded rough, very rough to me. I attribute this to the fact that the cap safety gap was firing 'all over the place.' But then again, the safety gap firing is akin to a misfire; You would expect rough operation under those circumstances, yes?
Thanks,

Daniel,
Using a sync rotary, the safety gap should never fire unless some problem occurs. Also the firing should never be rough with a sync rotary. A common problem is that the main rotary gap spacings are set too wide. Often they must be very close such as 0.010" or 0.020" for reliable steady smooth firing. The unsteady firing may be contributing to the racing sparks too.
