I've removed the flyback and there is no insulation missing from the filament loop at all. The "tire" has an area where it looks slightly melty, but only slightly. I'm going to get it nice and insulated with the afore mentioned sensor safe silicone, attempt to get the filament loop as far away from it as possible and reinstall with the old 1X2.
One thing that struck me as odd was there was already three or four pieces of electrical tape squares stuck between the "tire" and the filament loop. Looks like the problem could have been there before when the set was in use.
This theory makes absolutely the most sense to me so far.

FAIL!
No more discharge from the fly to the filament winding but problem is not solved. Every time I get over 95v I get sparks on the inside of the old 1X2, and sparks plus a blue glow on the new 1X2.
Time for a new $35 capacitor.
