MAINTENANCE Spark Plugs Spark Plug Recommendations 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 at the intervals outlined in the Periodic Maintenance Table beginning on page 73. Refer to the specifications section for the specific spark plug to be used in your snowmobile 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. NOTICE: Using non-recommended spark plugs can result in serious engine damage.

Always use the spark plugs recommended for your snowmobile. Refer to the specifications section beginning on the page 106. 82
