22r carb idle screw ID help

Hello, got a 84 with the 22r and I am just trying to figure out what screws are what on the carb. I am guessing the screw circled in red is the fast idle and the yellow is the idle speed?

The FSM diagram I downloaded for an 85 carb has a different labeling than the carb diagram that autozone.com has.

Also I noticed that air/fuel adjustment screw still has the plug on it. At what altitude would that need to be adjusted? I am near Denver so say 5280ft.
