To adjust the idle speed on a 1986 Honda 250 four-wheeler, locate the idle adjustment screw on the carburetor, which is typically found on the side. Start the engine and let it warm up, then turn the screw clockwise to increase the idle speed or counterclockwise to decrease it. Adjust until the engine idles smoothly without stalling. Always ensure the adjustment is made in small increments and check the operation after each adjustment.
