One other thing which I wasn't sure about, but just verified. The bike runs
fine with one cylinder hooked to the distrubutor, but wants to die and/or
backfire when both cylinders are hooked up.

Not sure why having one good and one intermittent cylinder would make the
bike run worse than having one good cylinder only. Maybe the spark being
produced isn't sufficient for both cylinders? Maybe the coil or condensor or
whatever is charging quickly enough?

Okay, after months of teeth gnashing, I finally figured out what my bike is
doing to cause it run poorly, now I need to figure out why...

I finally hooked a timing light up to it, and set the timing pretty close,
but then I noticed something odd... The light wasn't flashing everytime for
the #2 cylinder...

A little more investigation, I realized that if I disconnect the sparkplug
wire from the #1 cylinder, the #2 cylinder fires everytime, but when I
reconnect the #1 wire, the #2 starts sparking intermittently. #1 always
fires everytime as far as I can tell, even if #2 is hooked up.

I have new points and a new condensor. The coil is an accel 8140c, I don't
know if that is a resistor coil or not but it was really hot after running
for a while. Anyway the coil is new, one of the desparation things I tried
earlier which didn't help. The distributor cap looks pretty poor, I wonder
if a bad distributor cap/rotor could be the culprit???

Let me know your crackpot theories...
