Can't get dwell high enough...

Hello again:

I am dealing with an unusual issue on a common '67 single-point distributor. I cannot get the distributor to come into spec regard dwell and point gap. Point gap spec out of the FSM is .014-.019 and dwell angle is supposed to be 28-32 degrees. Both of these are very common specs.

At .017 point gap I have about 11 degrees of dwell. I closed the point gap up to .014 and that increased the dwell to 15 degrees. At this rate the point will nearly be closed up before I can get the dwell where the book specs it and that's nowhere near normal. That's asking for a set of burned points IMHO.

This is annoying, because I went to much effort to set up the points with the distributor out on the bench. The distributor shaft is nice and tight with thrust within spec. it has not been rebuilt. The points are new old replacement stock Mopar points(in the old green box), the rotor is NORS Mopar and the cap is NORS Standard...for what it's worth.

How does it run? Well it runs good most of the time. The only time it doesn't run good is when I lean on the secondaries hard for a while, then it starts to miss. It also breaks up when you have it in neutral and hold the engine at about 3K....so, something's not right.

So...what is the general consensus when the specs won't jibe? Wear somewhere in the distributor? I did double-check my readings with two different "period-correct" dwell meters I have and they both agreed. Thanks for any advice.
