Sync Rotary Gap Problems

I've been working since Thankgiving on a sync RSG...found a 1725 rpm motor
...ground some flats (best way other than a mill was a belt sander with 60
grit)...baby locked up great...replaced thin wires with copper tube and
8awg...all set for some spectacular fireworks...no such luck.
The new gap is 4 rotating poles and 2 sets of stationaries 180 deg apart. The
coil fires up nice and smooth every time, but only at about half the spark
length compared to if I stop the rotary gap and let it sit stationary???? The
tungsten sure lights up then!
What am I doing wrong here??? If I increase the gaps, all I get is a humming
4KW transformer. I'm using 1/8 inch rods...are they too thin and quenching
I rotated the motor back and forth to get the best timing...???
