Holley carb help needed

I'm rebuilding a 600 CFM Holley vac secondary carb and I need some help with the accelerator pump discharge nozzle. I believe I lost some pieces. If you remove the screw and the discharge nozzle there should be a pointed valve like looking piece, then a roll pin type piece and then a small ball right? I think I lost the roll pin and the check valve piece (pointed piece). The diagram shows a small ball, and a ball weight, it looks like a roll pin? And then the pointed piece, right?
Thanks

careful man... the diagram isn't correct for all models.

some (like my 1850) just have the needle valve, nozzle and screw. oh and two lil gaskets.
If you were to put a ball in there you would break something.

Only the very early Holley carbs used the ball and weight. The newer ones all just use the pointed weight.
