Is this a Dynaflow issue?

Sometimes when gaining speed, the engine briefly stops responding to gas pedal. Car starts coasting. Two seconds later car responds to pedal again. Motor is NOT stalling. I have the Variable pitch dynaflow on a '58 Special. Wondering if it's a very slow transmission shift to 2nd gear? Transmission slipping? Transmission fluid level is fine. Dirty automatic trans filter, faulty converter pump? Vacum leak in the fuel vacum system? May be hesitation/faulty accelerator pump in carb?

Runs and drives just fine. Idle may be a little high, but car has no tach so a little hard to tell. As mentioned car just doesn't respond to throttle briefly, then few seconds later it's ok. So not a transmission issue huh? I did change the fuel filter in front of carb hoping that would solve it, but didn't do anything.

The new government subsidized corn for ethanol ( Corporate Welfare ), is causing a lot of problems. Take your carb apart and do this to increase atomization. - "Enlarging AFB channel restrictor to cure lean-off idle stumble" That is if you have a Carter Carb.
