I haven't seen all
the comments and am coming into it late, but was confused by Chris' voltage
readings.
IF I understand
correctly, the resistor drops voltage, and is wired such that it is bypassed
during the start sequence. Full voltage is available when you light
off the engine, but slightly less voltage is provided at all other times.
Bypassing the resistor temporarily will give the car a much hotter spark, but
will burn the points badly within a few days. If you do this three
times before you learn, it will burn the points three times. But that is
another story.
Resistance across the MOPAR ballast resistor is
about 0.5 ohms, if memory is working. Voltage on the battery side should
measure above 12V, around 13-14, if all is well. The other end should be
closer to 10-12 volts; six sounds low to me. Can't find the FSM to be
certain. Will look more.
I didn't quite
follow the test results, but with everything hooked correctly,and the car
running, measure voltage to ground on the battery side of the resistor, and
then on the other end. This is a cheap part, and easily replaced. If
you have any uncertainty, replace it. If it's cured, buy another and put
it in the spare parts bin. If not, leave it in place, and put the one you
removed in the spare parts bin.

What about the fuel tank & lines? Is
there a lot of junk in the tank that's finding its way into the carb? Any pin
hole leaks in the lines that could be sucking air? I'd remove the inline
filter & empty the gas onto a paper towel or something so you can see is
there are rust particles in the gas.

I've recently gotten
some hard lessons on dirty gas. I am working with small engine equipment
in Chad, where the finest gasoline comes conveniently packaged in old whiskey
bottles with a rag stuffed in the top, suitable for fuel, or ready to light and
throw. We lost a couple of pieces of equipment before realizing just how
bad the fuel is. I strain all gasoline twice through coffee filters before
it's run. It is amazing how much very fine particulates remain suspended
in fuel that looks acceptable. A little bad gas can cause you trouble for
a long time.
Good luck with
this.
