49,
This is worth a try! Remove the fast idle stop screw from one of the carbs. Use the other carb as "Control" and adjust the cold idle with the control carb. You can slow the fast idle down with one screw to the point that your chokes work and the total air/fuel flow is comparable to a single carb.
I've never run just a pair of 2bbls, only in threes. We would remove the chokes from the front and rear units and run fast idle on the center carb. I always left just enough travel in the linkage, (progressive, of course) to let the front and rear carbs stay at idle until just above the point of fast idle on the center carb.
Think of the twin carb setup like it was a mechanical four barrel that is NOT progressive!
I'm sure you've probably already thought of this, but just in case you haven't.....
