I have a newer Edelbrock 1406 carb on a street car. I had it apart chasing a stumble, and no accelerator pump squirt. Under the acc. pump nozzle is a little brass looking needle (flat on each end though) with a ball under it. The Edelbrock carb book shows in multiple illustrations of a small spring under there also. Can someone tell me what is suppose to be there? Spring, ball, needle, and in what order??? thanks
