Holley 670 street avenger problem

I have the 770 on my 360 and it works great but when I first got it I had to bend the linkage to get the accelerator pump to work instantly. It worked when you moved the linkage to about 1/4 throttle but not instantly. Just had to tweek it a little to get the pump adjustment right. You may have a very simple problem, look down and work that linkage a little to see what happening. Thats my 2 cents.
