I'm hoping someone can help me out. I was rebuilding an old holley 1371-1 Carb for my 58 F600. As I was putting it back together I realized that the pump operating lever adjustment screw is missing. I still have the nut and the spring but the screw is completely gone. I'm sure I can just go down to the hardware store and pick up a new screw but I need to know how long it is supposed to be.

 

Your 1371-1 is a model 2300 , I measured one of my 2300 it was 1 1/4 " total length . Hope that helps
