If your Exmark Lawn Mower engine won't start, starts hard, or fails to keep running, try these steps: * Fill the fuel tank. * Open the fuel shutoff valve. * Add oil to the crankcase. * Ensure the throttle control is midway between the “SLOW” and “FAST” positions, and the choke is in the “ON” position for a cold engine or the “OFF” position for a warm engine. * Replace the fuel filter. * Clean or replace the air cleaner element. * Check the seat switch indicator; replace the seat if needed. * Check the electrical connections for good contact. Clean connector terminals thoroughly with electrical contact cleaner, apply dielectric grease and reconnect. * Clean, adjust, or replace the spark plug. * Check the spark plug wire connection. * Replace module.
