The second picture is of the AC idle up dashpot. . .but the vacuum lines are misrouted. There is a plugged hose (in your picture) behind the carb that normally supplies manifold vacuum to a solenoid which gets energized when the AC is turned on, which is then supposed to supply vacuum to the dashpost. . .the hose doesn't normally run directly to the carb, like in your picture.
the hose you are touching in the picture is added . . . I think it is a vent only.
