What I have observed with a badly worn distributor is that the points gap is inconsistent as the cam rotates which...

A: Makes it impossible to set the points gap correctly.

B: Creates a situation where the points gap is much too small for decent operation
on one or more cylinders, but still works decently on the other cylinders.

The amount of time that elapses between having the engine run (more or less) with such a distributor, and run like crap can be very short when an erratic points gap is concerned; there seems to be a point of wear at which the performance degrades very rapidly, even within a day, in my experience.

Pertronix ignition is very, very good.

And no, I'm not insisting the guy's problem is ignition related, although an ignition problem isolated to one or two cylinders can make it appear as if one of the carbs are not working correctly.

Looking for fuel system contamination is certainly warranted.
