CJ, I see you have a wealth of knowledge and answers on here. First of all, thank you for your service.
I have owned at least a dozen jeeps. I recently bought a 1978 CJ7 with an AMC 304 motor. The previous owner(s) have tweaked the motor, it has a cam. When I first drove it, it sputtered and drove terribly. First mechanic I took it to stated coil was hooked up backwards and they put new coil in and removed, yes removed the resistor! Ran crappy.
Took it to the next mechanic and he discovered no resistor problem and put one inline to the positive side of the coil. I see you mentioned that in another thread that is no go. It ran like crap. Mechanic said couldn't fix it some thing is wrong with the engine.
Third mechanic I took it to, said the problem was that the carb was full of crap! Ran great! Until Thanksgiving day! Turned over and it started briefly. I continued to turn it over, several loud super loud backfires (it has cherry bomb mufflers) no crankie. Spark was weak. The next day, I decided to check the coil. Ohm resistance was out of spec so I bought another one and change the coil myself (got one from Autozone specifically for this make and model). There is nothing on the package that says for use with or without a resistor. It's "Hecho in Mehico" duralast. However, in my diagnostic I did check it again.
Okay I am taking a breath and going to let you read this before I get too far into this.
have the same problem?
