ADULT SECTION Maintenance Carburetor Protection During Off-Season Storage When preparing your snowmobile for off-season storage we recommend that you add a fuel conditioner/stabilizer or Premium Carbon Clean (2871326) to the fuel tank. Follow the instructions on the can. Run the engine for five minutes to get additives through the entire fuel system. Then top off with fresh fuel and turn the fuel valve to OFF. If stabilizer is not used, make sure the fuel valve is OFF and drain the carburetor. Catch fuel in a container or shop cloth. Remove the spark plug and pour approximately 5cc of engine oil into cylinder. Slowly pull the recoil starter so the engine turns over two or three times.
Reinstall plug securely. Position piston at bottom dead center (BDC). Observe all fire safety rules when draining carburetor. See gasoline warnings on page 46. Slowly pull the recoil starter handle until resistance is felt. Leave it in that position. Clean the engine thoroughly with an oiled cloth. If stabilizer is not used, turn the fuel valve to OFF. Remove the strainer cup, place the strainer over a container, and open the strainer cock to discharge fuel from the fuel tank. Remove the carburetor float chamber bolt from the bottom and discharge fuel from the carburetor. Replace bolt. 65
