MAINTENANCE Extended Storage Engine Protection Proper preparation of the engine and fuel system is vital to the prevention of rust and corrosion on precision engine parts during storage. Whenever the machine is stored for a period of more than 60 days, the engine must be fogged with fogging oil. Follow the engine fogging instructions provided on the can. See page 128. Always add Premium Carbon Clean or a fuel conditioner/stabilizer to the fuel tank. Follow the instructions on the can, running the engine for five minutes to get additives through the entire fuel system. Top off with fresh fuel. Using a fuel stabilizer and topping off the fuel tank eliminates the need to drain the fuel system. If you prefer to drain the fuel tank, use the following procedure: 1. Transfer unused fuel from the fuel tank to an approved fuel container using a siphon pump. Do not re-use fuel after storage. 2. Securely support the front of the snowmobile with a jackstand so the machine is elevated and the engine is tilted rearward. 3. Remove the spark plugs. 4. Rotate the engine slowly, watching the pistons until they're at bottom dead center (BDC), the lowest position in the cylinder. 5. Pour approximately one ounce of engine oil into each spark plug hole. 6. Repeat step 4, then replace the spark plugs and lower the machine to the floor. 116
