Longgone-
I did this the other day, and it did spark, but it appeared to be a weak spark to me.
I tried it directly off the coil today and it was a nice bright spark. The spark at the plug the other day could have been OK, and just appeared to be weak, but I can't be sure now. I'll have to do it again tomorrow.

I replaced the dist cap with another used one I have and it made no difference at all.

I also bypassed the ballast resistor via a power wire from the battery directly to the coil. Made no difference.
