I do have a ballast resistor. I even replaced with a spare as it was getting a few years on it. I'll do that test here in a day or two and see what I find. I'll try a spare coil on there too, currently using an MSD blaster.

I'm at 1.5 turns out on the mixture screws. Not running on fast idle cam, I gutted the choke mechanism quite a while back. The linkage is free and the throttle shafts are also good. My guess is that its right on the edge of idle/main circuit given the idle rpm. Again, in gear it fluctuates around 800 or so. The battery is new and the alternator tested fine also.
