Spark Plugs
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.
Refer to the specifications section for recommended spark plug type and gap.
NOTICE
Using non-recommended spark plugs can result in
serious engine damage. Always use the spark plugs recommended for
your snowmobile.
Spark plug condition is indicative of engine operation. The spark plug firing end condition should be read after the engine has been warmed up and the vehicle has been driven. Immediately check the spark plug for correct color.
WARNING
A hot exhaust system and engine can cause serious
burns. Wear protective gloves when removing a spark plug for inspection.
