Question Needle-Valve adjustment for O.S FS26

Hello everyone, I have a question for how to adjust a used FS 26 engine, which I clean it up and rebuild.
I saw the user manual, which it is very clear to say ""Turn the needle-valve in the direction of arrow from the closed position. FS-26S (3 to 3-1/2 turns) FS-40S (2-1/2 to 3 turns)"".
But, how about the Small Needle? which is the screw on the cab, to control the fuel for idle.

Thanks
Chris
