The wiring has been re-done and not exactly as original but ignition switch works fine and good power to coil.
I saw on a Ford forum that one problem may be with insufficient point gap: I just can't get up into the diver helmet distributor to check the gap etc. I can just barely see the one set of points with a mirror.
If I take off the distributor will I screw up the timing when putting it back on? I haven't been able to find any good information and photos on fooling with these distributors.
Oddly, right after making the post I went around the block with modest power, babying with the choke seemed to help a little bit. No idea if I tinkered with something that helped a bit.

The timing is set inside the distributor by adjusting the plate that the points are mounted to. I used to just scribe the plate before removing it from the distributor.
Remove the entire distributor as a unit. It has been a while since I have done one, but I recall it was 4 5/16 bolts (1/2 socket size) and the distributor will come right out with the vacuum line and the wires removed.
MBF1, or any of the Ford CMP manuals will give you a good description on how to repair the distributor. Seems to me you used to have the timing fixtures in your inventory. They make setting the points and timing a breeze. Again, follow the steps in the manual. While you have the point plate out, that is when you check out the weights and the vacuum advance. Merely sucking on a tube you attach to the vacuum advance will easily indicate if it is working or not. Lightly oil the weights on their pivot points any time you are in a distributor.
No doubt about it....it is a tight fit removing the distributor. But once done right, you will not have to go into there again for many many years. If you find it too tight, remove the radiator....lots of room then.
