I finally got around to testing the coil today. At the extreme raised 
height, nothing went wrong. I lowered it back down to 2 inches above the 
primary and it immediately sparked to itself. So as long as I keep it very 
high above the primary, nothing goes wrong. (at least it didn't just burst 
into flames)  Does keeping the secondary that far above the primary reduce 
the performance? Would I be better off to wind a new secondary? I actually 
have enough leftover pipe and wire left to redo it if I have to, but would 
rather fix it instead of winding all of that wire again...

There is a very good chance that you have damaged the magnet wire insulation
with the paint thinner. It removes polyurethane and also the magnet wire
insulating coating.

It will be interesting to see what happens when you power it up again.
