I hope this might help others. I have been fighting this carb issue since the resto of my ccpu. just could not get it to idle well. I had even rebuilt another complete carb but downfall was I used the same throttle shaft. the shaft I used was all steel and had a milled recess where the butterfly sat not a slot like the brass ones which in turn blocked the idle hole in the throat off. changed to slotted style shaft and idles perfectly. I dont know if the all seel shaft is supposed to have a different butterfly or its just an oddball. hope this may save somone some grief
