      Terry MartinAug 4, 2025
      If your Exmark Lawn and Garden Equipment engine won't start, starts hard, or fails to keep running, several issues could be the cause. First, ensure the fuel tank is full. Next, check that the fuel shutoff valve is open. For a cold engine, make sure the choke is in the 'ON' position, or 'OFF' for a warm engine, and the throttle control is midway between the 'SLOW' and 'FAST' positions. Also, inspect and replace the fuel filter if it's dirty, clean or replace the air filter if it is dirty, and ensure the traction lever is in neutral. Finally, check the spark plug wire connection and clean, adjust, or replace the spark plug if faulty.
