Did you check the float level and do you have good fuel supply?
You can visually check the action of the accelerator pump by looking down
the carb. Check for fuel flow and duration by the throttle position. You
may not have the correct pump cam or it maybe in the wrong mounting
position.
At mid rpm and up the main metering jets and power valve are supplying all
the fuel. It's possible the power valve is not functioning or is the wrong
number.
Hope this helps

Subject: Carb problems?
When I accelerate from stop the car initially pull very strongly and
then begins to stumble. If I then let off the gas and open it very
slowly I can "catch" it and get it to accelerate normally. This is
happening anytime I open the throttle at mid rpm. When I rebuilt the
carb the kit that I used did not include a new accelerator pump
diaphragm or spring could this be the problem? If so which spring
should I use. I'm running a holley 1948 with an F4B.
Thank in advance.
