Since it's cheap and easy, swap the resistor and see.
However, it sounds to me that your carb is flodding which would be a problem with the floats, and possible other items. Get a carb kit and tear it down.

SOUNDS LIKE A CARB PROBLEM. WHEN IT ACTS UP AND DOES START DOES IT LOAD UP AND BLOW BLACK SMOKE? WHAT KIND OF CARB DO YOU HAVE? IF ITS OLD ESPECIALLY IF ITS A HOLLEY YOU WOULD PROBABLY BE BEST TO GET A NEW CARB. OLD CARBS IF THEY ARE WARPED YOU COULD GO THRU THEM TIME AND TIME AGAIN AND GET NOWHERE. IF YOU HAVE A HOLLEY GET THE GOOD FACTORY HOLLEY METERING BLOCK AND PLATE GASKETS NOT THE RUBBER MOROSO ONES. MY CHOICE GET A EDELBROCK,NO GASKETS BELOW THE FUEL LEVEL GREAT FOR A DRIVER. IF YOU WANT SOME ADDED POWER, PULL THE INTAKE, BLOCK THE HEAT RISER PASSAGE FROM THE HEADS,AND FIX THE HEAT RISER VALVE IN THE EXHAUST MANIFOLD SO ITS WIDE OPEN. OF COURSE WITH THIS SET UP THE CHOKE WILL NOT FUNCTION.YOU WOULD HAVE TO WARM UP THE ENGINE FOR A WHILE BEFORE BEFORE DRIVING.
Rebuilding the carb is what I'm looking at as well. Its a Carter AVS 4 Bbl. OEM on the '68 383 that came with the car. My father in law has a carburator cleaner bucket system of some kind. Pull the carb, soak it in the bucket with the cleaner for a day or two, blast it with air, let dry and tear it down, rebuild, and there you go.

Gary, tear it down and soak the parts as you go. Carter carbs are a breeze to rebuild, just follow the numbers on the instructions. To reassemble just reverse the process.

Snotty is right. Carters are a breeze to build. Much better than a holley. Just make sure you get air through all the tiny holes and ports after soaking. Soaking will loosen crap that builds up over the years in those ports and may block them later a vacuum starts to run through them.
If you have one, try to use a rubber tipped blow gun to prevent damage and to be sure you move the full force of the air through the ports. Hydraulics would be best. I strongly suggest you look up some Berkable 2+2 Carb Cleaner too. Blows the doors off anyone elses. Force some of that through the small ports first and chase it with air.
Done probably 50 of those AVS's over the years. . . A couple of them are still running around.
71F3, would you please post some information, such as corporate web address or phone number, for the carb cleaner you recommended a few replies ago. I can't seem to turn up any information about it. I'm always on the look-out for a good product and would like to give it a shot. Thanks
