    How to start a 909 Lawn Mower that won't start?

      If your 909 Lawn Mower engine won't start, first check if the fuel tank is empty and refuel if needed. Also, check the oil level using the dipstick and add oil if it's low. Inspect the spark plug for dirt or wear, cleaning or replacing it as necessary. Ensure the cutting height is set high enough, so the blade doesn't hit the grass when starting. Drain any old fuel from the fuel tank and the carburetor bowl. Finally, make sure the On/Off switch is set to 'I'.

      If your 909 Lawn Mower's cutting or engine performance is decreasing, try increasing the cutting height using the height adjustment lever. Check the blade; if it's dull, replace it with a new, sharp one, remembering to turn off the engine first. Also, ensure the grass catcher isn't full; empty it if it is.

      If your 909 Lawn Mower engine won't stop, try depressing the “O” on the On/Off switch. Remove the spark plug cap. If that doesn't work, allow the motor to run until all the fuel is used. Do NOT leave the mower unattended.
