Buying that (pricey) kit to use as a replacement DS2 harness is a bit silly, unless someone is real insecure about their wiring skills........

I did say "WE" 
And understand that their kit is a 'universal' harness.
If I were to buy that kit I would have another useless geegaw sitting in my electrical scrap box.
This part might come in handy for somebody I suppose.
Did points ignition Fords run full voltage to the coil?

Nope. They also used the inline resistor. Of course, it was also bypassed during cranking, like the DS2, for the same reason (hotter spark).

Not really. It is needed on any Ford that is getting the entire ignition harness, from the switch out, replaced and will be using a DS2. Painless doesn't have the original style resistor, even as an option, in their Ford wiring kits. They set these up like a GM, having full battery voltage from the switch, in case someone is using a GM dist, or worse, a GM engine.........

I didn't realize you could use a DuraSpark distributor at the back of a Government Motors engine?!?!?
It makes sense (I guess) if you are completely rewiring a car.
Or just want that "cool" ceramic resistor screwed to your firewall.

OK, I started messing with the tuning today. I disconnected the advance and plugged all vacuum ports.
The vacuum peak was at 20 Hg , but the timing was at 24° to get that. The truck would start and run like that. However, it didnt want to shut off when I turned the key off.
I ended up down at 14° and the diesel was just barely there when I shut it off. It was starting to grunt there when starting. The vacuum dropped to 15Hg at that setting as well.
Whenever I hooked up the advance the idle increased about 500 RPM. Also the with the advance hooked up the light showed something like 36° at idle.
I am a little confused on where to go from here.

If you look at pg 2 of this link there is a pic of an Edelbrock carb with the vacuum ports diagrammed. On the bottom right of the front there is a port that is labeled as "manifold vacuum , distributor vacuum advance port for non emission controlled engines". Then there is one on the left side labeled " Timed Vacuum, distributor vacuum advance port for emission controlled engines. I hooked it to the one that on the right for non emission controlled engines.

It's dieseling because he has the stop too open.
