This is my first time rebuilding a carb. Did not pay attention when removing the screw plugs. I have one screw plug (per carb) that is a rounded head and one that is a hex head. Parts breakdown only shows one part number any idea ? They both fit. Part #9

Maybe previous owner had to replace and didn't want to spend $9 for a small screw. ????

That would be my guess. As long as it works and seals, go with it.

I like how the diagram shows two different orifices with the same item number.
