  Kevin DiazAug 13, 2025
  To start your Cub Cadet Lawn Mower, ensure the knob is in the disengaged (OFF) position and the parking brake is engaged. Connect the wire to the spark plug and place the throttle lever to the FAST position. Pull out the CHOKE control and fill the tank with clean, fresh gasoline (less than 30 days old). If it still doesn't start, clean the fuel line or replace the fuel filter. Clean, adjust the spark plug gap to .030” or replace the plug.
