MAINTENANCE Spark Plugs General Maintenance A new engine can cause temporary spark plug fouling due to the preservative added during the assembly process. Avoid prolonged idle speeds, which cause plug fouling and carbonization. Change the spark plugs every 2000-2500 miles (3200-4000 km). CAUTION Using non-recommended spark plugs can result in serious engine damage. A spark plug with a heat range too high will always cause engine damage if the engine is operated in conditions more severe than intended for that plug. Always use the spark plugs recommended for your snowmobile. S S S S Use recommended spark plugs with the proper gap. Use only resistor-type spark plugs. Torque spark plugs to 18-22 ft. lbs. (24-30 Nm). Always carry spare spark plugs. 78
