[T3] Problem solved, but Why?

[J. Jonik]

How to describe the "fluttering"?  Hmmm...I thought Woody Guthrie did it ok in the You Tube....but,  slow it down from his fast speed to maybe 23 1/3 rpm...deeper, rounder.   Kinda like gas was being machine-gunned into the system instead of smooth flow.
  It didn't seem like it was just running on 3 cylinders....it was like it was going over those ridge noise bumps in the road before you get to toll booths, or on the sides of some highways to wake you up from drifting.   It wasn't just the sound, but the vibration.

 After running great after previous problems solved by replacing Voltage
 Regulator, suddenly, on sleeting day, engine started fluttering, 
vibrating, etc, at one point not wanting to rev with acceleration in 
first gear.

Rotor and cap contacts are irrelevant, since, as Keith points out, 
the spark jumps an air gap there anyway. The air is a MUCH better 
insulator than any corrosion.

My vote would be for the ignition points. If they were set too close, 
they might not have been opening reliably.

I'm not sure what you mean by "fluttering." I'm not familiar with any 
symptom that I would describe with that word.
