Are you using the same intake and carb as before the rebuild? If not, put the old carb back on and try it out. If it's the same - with a different cam you will most likely need to recalibrate that 1407. Is it using the stock calibration? Do one thing at a time. Put the pump shot linkage in the lower hole. If no good, try to top hole. Then proceed to change rods and springs to get it dialed in correctly. I also found that on these carbs with mechanical secondaries, you might experience a bog on acceleration because the secondaries are coming in too quick. You can bend the linkage rod and have them come in later. Made a big difference on mine.
