If your kit were for a Holley carb, it would not have worked for your Carter. Like Chryco said, look down the throat of the carb and wing the throttle. There should be an immediate shot of fuel into the carb throat, and it should continue until the pump bottoms out in its bore. If there is a shot of fuel, then it is probably a matter of fine-tuning what you have. On the Carter BBD, the pump stroke can be increased or decreased, to help tune the accelerator pump circuit. Measure the height of the accel pump rod above the top of the carb, and record it for future reference. Then, bend the link, or move it to a different hole in the pump arm (whichever is necessary to get the desired change), to increase the stroke of the pump. This will mean putting more of the pump rod above the top of the carb, and small changes can make a big difference. If no change in performance can be gained, then you put the pump rod back where you found it, and check for another problem.
