You stated it idles great & drives great so that would indicate the pump,squirter's & float level are OK.
It sounds like you may have to work on the transitions.
1st. pull the carb & adjust the primary's for .020 exposure of the slot, you need at least that to accomplish a seamless tip in. install the carb, warm up car--short drive, if idle is too fast, reduce speed with secondary adjustment.

If that doesn't solve the problem you may have to start messing with the Idle air bleeds or restricters.
