Sparkle-ing discharges and Banging SRSG ? ? ?

Running my coil again for the second day.  I moved the stationary electrodes
approximately and extra 1/2" away from the rotor of my SRSG which helped a
bit.  However, I am still having
the following problems:

1.  Getting sparking type flashes (small) at the toroid itself all over as
arcs start forming or at least it appears that way.

2.  Getting more flashes (arc-overs) at my SRSG between the stationary
electrode and rotor (so it seems)


Anyone know the cause of problem 1 above????   Also, are the arc-overs
(flashes) i'm getting at my SRSG due to a too small rotor, too close
proximity between stationary electrode and rotor, or something else in the
system that isn't tuned right.  This all increases as I increase power
(using my variac).  Perhaps my SRSG isn't tuned properly???

Right now, i can only go about 75% power.  Otherwise, I start getting the
problems above.
However, at 75% i am getting 40" streamers (measured) with occasional ones
hitting about 45" (measured) so it seems pretty good thus far.

Any help appreciated.
