The carb has two adjustments on the outside for idle speed and mixture. First, with a warm engine I would get it to idle at specified RPMs, or as close as you can get, by adjusting the screw on the linkage. Next I would start adjusting the idle mixture screw on the base of the carb. Screw it in until the engine starts to slow down then back it off one-half turn. You may need to go back and forth between the idle speed and the idle mixture to get a final setting. Also, be sure the choke plate is fully released.

If the engine will only run with idle mixture screw turned in all the way, then you have a flooding carb. This is caused by an incorrect float setting or the needle and seat valve not seating properly.

Finally, with the engine idling at the specified RPMs recheck the ignition timing and adjust if necessary.

You have had your troubles in getting this engine to run since Salado (I was the driver of the black 55 Clipper), and are making good progress. Let us know how this works out.
