I've adjusted the accel pump linkage so I know it's right.

Try closing the choke blade some or put your hand over the top of the carb to richen it up some and see if it gets better. If it gets worse pull a vacuum line off and retry.

Any chance you have a video of this car running? I’m considering the 2802 in a 400 I’m putting together and was wondering how it sounds?
