How do you adjust idle in a 1974 super beetle?

To adjust the idle on a 1974 Super Beetle, first ensure the engine is warm and at operating temperature. Locate the idle adjustment screw on the carburetor, typically found on the side of the carb. Turn the screw clockwise to increase the idle speed and counterclockwise to decrease it, checking the RPM using a tachometer if available. Finally, make small adjustments and listen for a smooth, stable idle before securing any adjustments.
