Not to contradict the other learned opinions, but I think if the idle is not right either, your problem is not fuel starvation (which would be the result of a plugged fuel filter). My guess is that you opened the secondary side of the carburetor for the first time in a long time when you floored it, and thus allowed things to move that haven't moved in perhaps eons. So I'd start by inspecting the secondary side of the AFB - in particular, make very sure that the secondary throttle butterflies have totally seated in their bores - this linkage gets very balky with atrophy when the secondaries have lain asleep too long - and one of the most common symptoms is exactly what you describe, due to the secondary throttle butterfly valves not closing all the way. Take a can a spray carb cleaner and really clean up the secondary lockout hardware, and make sure everything works smoothly, in particular the odd shaped plate that interferes with the secondary opening mechanism on the driver's side of the carburetor during choke operation. D^2 wouldn't know about this problem, since he always drives with the secondary side wide open!
