<VV> '62 Wagon Gasps

[Ron]

My '62 doesn't like to take the gas from an idle and prefers to gasp and die.  I've replaced the pump rod cups and bench adjusted the carburetors per the manual to no avail.  Throttle actuation gives a good (it seems to me) squirt of gas in each one.  I suspect the carburetors as they did the same thing on another Corvair before I worked them over and put them on the 62.  What's the next most likely item to suspect?
