Holley Experts anyone?

Need help on particulars for a Holley 780 w/vac sec. Took one apart and might've lost a part. The problem is the primary pump discharge nozzle assembly. From the discharge nozzle screw down.. what are the exact sequential parts required? I have a schematic but I'm not sure if I need this part. My schematic shows this from the top down:
1. pump discharge nozzle screw
2. pump discharge nozzle screw gasket
3. pump discharge nozzle
4. pump discharge needle
5. pump discharge ballweight
6. pump discharge checkball
The items in question are 5 + 6. When the carb was torn down I don't believe there were these parts, instead what I found were parts 1-4, not including 5 + 6. Help from the Holley crowd please. Thank you for any help offered.

There is a checkball under the screw to keep fuel from siphening out. There is also a gasket under the squirter. Screw, gasket,squirter,gasket,checkball.

On some carbs there might be a check ball or the needle but I don't know of any carbs that use both. I think you have everything you need.

Thank you for all the input. The Holley instruction sheet that came with the "Trick Kit" was very vague and somewhat confusing. The consensus is just the needle, or the ballweight and check ball but not both. Thanks for the input, I'm a rookie at this, as of late. Years ago this was my full time hobby. Now my family is my full time hobby and this stuff is a.....whenever time permits.
