1. Identify the carburetor: The carburetor is usually located on the side of the engine, near the top. It's a small, metal device with a fuel line attached to it.
2. Look for the idle screw: The idle screw is usually located on the side of the carburetor, near the bottom. It's a small, metal screw with a spring around it.
3. Adjust the idle screw: To adjust the idle speed, turn the idle screw clockwise to increase the speed or counterclockwise to decrease it.
Note: The idle speed should be set so that the engine runs smoothly without bogging down or racing. If you're not sure how to adjust the idle speed, refer to the owner's manual for your mower.
