[JAGNUTS] Thanksgiving puzzle

[Andrew]

I would appreciate your help in diagnosing the following problem. There could be prizes!

the 73 MGB GT ran fine one evening. The next day, it turned over fine, fired a few times but would not run. There is ample fuel, a coil swap made no difference, there is good spark on the coil wire going to the dizzy, but there does not seem to be a spark when grounding  any of the sparkplug lead ends. The points and condenser were replace a few months ago, and the points are properly gapped. When the ignition is on, there is only a slight spark/arc when manually opening/closing the points. I don't have a spare condenser, so I haven't test-swapped it.

any suggestions?

thanks
