Roller, you questioned the function of the screw on the right side of the photo, and in the next post
bracurrie explained to you that the screw is
not a mixture screw; it is an air screw.

It is adjusted along with the idle mixture control on the MIP to adjust idle.

Again, you were able to lower the idle speed by reducing the amount of
air entering the manifold by closing the air screw.
