ADJUSTING THE IDLE SPEED
If the engine will not idle properly:
1. Start the engine. Refer to Starting and Stopping.
2. Release the throttle control and let the engine idle.
NOTE: Make sure the blade is not in contact with the ground when adjusting the idle speed.
• If the engine stops, increase the idle speed. Use a small Phillips screwdriver to turn the idle
speed screw clockwise, 1/8 of a turn at a time, until the engine idles smoothly (Fig. 23).
• If the blade spins when the engine idles, reduce the idle speed. Turn the idle speed screw
counterclockwise, 1/8 of a turn at a time, until the blade stops moving (Fig. 23).
WARNING: The blade may spin during idle speed adjustments. Wear protective
clothing and observe all safety instructions to prevent serious personal injury.
