I took the liberty of pasting your email in here ahead of my response because it confused me and maybe someone will enjoy your puzzle.

My confusion here is that in my previous post, I wondered if your mechanic would still think my coil was bad, even though my condensor read 5 K ohms, proving that it was bad. I don't recall ever mentioning that condensors rarely fail. In fact, even though I have not seen too many failures, I would assume that they are failure prone, or why would points and condensor normally come together in a tune up kit?

Without the clue, I would have to suspect anything and everything in the ignition circuit, from the magnets in the flywheel to the plug. Given that the clue is "noise", I have to guess you mean RF noise and the plug suppressor cap was bad. I am not sure how you solved it by removing the spark plug, my ped won't run worth a hoot without one.
