Hi Richie, all,

The tops of the secondaries are connected together with flexible 
metal hose, and this is connected to the extra coil with a copper pipe.
I suppose a voltage does reflect back to the other secondary and
primary, but doesn't seem to cause a problem.

The "window" for acceptable operation is extremily narrow.  I suspect
this is due to rotary gap timing jitter, which is forcing the offset to be
set wider than theory would suggest.

I'm sure the second bang is building onto the first spark growth wise.
The question is; is this better or worse, or the same, as equally spaced
firings, spark growth wise.

And a big thanks to all who have made suggestions so far.

Thanks,
