Hot starting issues

I can only answer from the information given.
There are only TWO reasons that you can, on a MOPAR, have spark in crank but not in run. The first is the ballast and the second is the ignition switch. The ballast has been replaced and Dell showed you all about the wiring. If you follow his advice, you will no longer have a spark-issue.
My second post#21 is pure speculation on my part, assuming that you don't/didn't/nor ever did have, a spark issue, lol, and based on my experiences.
However, with just 10* of idle-timing and the mixture screws "half-way out" what ever that means..... you should be ok.
My question is this;
If you set the mixture screws with a vacuum gauge, when does it smell rich, lol, and where are you smelling, and when.
As for me, I don't use a vacuum gauge for this...... cuz most of the time it just never lines up to what the book says it should.
But fix your spark first, and then we all can deal with the carb later.
