The one on the rear of the carb, the one on pass side is your high idle.

Without a more specific identification of the carb it is rather hard to pinpoint the locations of the screws.

Generally speaking the screw that controls the throttle plate position at curb idle is most often referred to as the idle speed screw. Its tip will make contact onto the linkage.

Then there is at least one idle mix screw, threaded into the body of the carb and it controls the fuel flow needed to support a steady curb idle.

And then the fast idle speed screw is most often located behind the choke assembly.
