My 1955 Chris Craft with a Her

My 1955 Chris Craft with a Hercules KBL starts great and runs fine except when I want to go from around 1000 RPM to full throttle. It usually stalls or hesitates unless I pump the throttle.
It has 3 Zenith carburetors on it. What should I be looking for in order to correct this problem?
 
An accellerator pump in a carb

An accellerator pump in a carbureator with a worn out seal or needs the amount of travel adjusted.
