How do you adjust the idle on a 2 barrel Rochester carb?

To adjust the idle on a 2-barrel Rochester carburetor, first ensure the engine is warm and idling. Locate the idle mixture screws on either side of the carburetor; turning them clockwise enriches the mixture, while counterclockwise leans it out. Adjust each screw slowly, listening for the smoothest idle and optimal RPM. Finally, set the idle speed using the throttle stop screw to achieve the desired idle RPM.
