MAINTENANCE
Extended Storage
Engine and Carburetor Protection (Carbureted Models)
Proper preparation of the engine and fuel system is vital to the preven-
tion 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 container.
Always add Premium Carbon Clean or a fuel conditioner/stabilizer to
the fuel tank. Follow the instructions on the container, running the
engine for five minutes to get additives through the entire fuel system.
Top off with fresh fuel. Do not allow the snowmobile to run out of fuel.
If stabilizer is not used, drain the carburetors by removing the water trap
drain plugs. See page 84.
Jet restriction caused by improper storage can cause lean conditions and
very poor slow speed driving quality.
