car stalls on hard accel

Yesterday was the first day i got to really drive my duster around town and i found a problem, whenever you goose/nail the throttle from a stop or low speed, the car stalls.

A friend of mine says its probably the accelerator pump and that my carburetor needs a rebuild. Is there anything else that might cause this problem?

I have an edelbrock 1406 carb w/ electric choke. And i found a frayed wire coming from the electric choke.(not sure if that would cause a problem.)

Otherwise the car runs fine.
