Ted,

You may benefit greatly by using a non-sync rotary with that system,
and adjust the break-rate for best spark output.  The clue is that the
static gap gives better performance than the 100 bps SRSG.  This
means the cap is a little small for 100 bps.  By using a non sync
rotary, you can use 180 - 350 bps perhaps, and let the spark grow
via bps.   As an alternative, you can try using 200 bps sync.  
I assume you optimised your ballast setting which is very important
at 100 bps.
