  If your Exmark Lawn Mower engine won't start, starts hard, or fails to keep running, several factors could be the cause. First, ensure the fuel tank is full and the fuel shutoff valve is open. Check the oil level in the crankcase and add oil if it's low. Make sure the throttle and choke are correctly positioned. Other potential issues include a dirty fuel filter (replace it), a dirty air cleaner (clean or replace it), corroded or loose electrical connections (check and clean them), a faulty spark plug (clean, adjust, or replace it), or a disconnected spark plug wire (check the connection). If these steps don't resolve the issue, consider contacting an Authorized Service Dealer.

  If your Exmark Lawn Mower engine loses power, it could be due to several reasons. Start by reducing the ground speed, as the engine load might be excessive. Check the air cleaner and clean or replace it if it's dirty. Also, verify the oil level in the crankcase and add oil if needed. Make sure the cooling fins and air passages for the engine are not blocked; remove any obstructions. Check the fuel cap vent hole and clean or replace the fuel cap if the vent hole is plugged. Replace the fuel filter if it's dirty. If the problem persists, contact an Authorized Service Dealer.
