Off season or extended storage of your snowmobile requires preventive
measures to aid against deterioration and to prolong the useful life of
many components.
Fog the Engine
1. Treat the fuel system with POLARIS Carbon Clean. See page 76.
2. Support the front end of the machine so the engine is level or tilted
slightly rearward.
3. Turn the fuel valve off.
4. Remove the spark plug.
5. Pour 5cc of Premium 4 Synthetic 0W40 engine oil into the cylinder.
6. Slowly pull the recoil starter to turn the engine over two or three
times.
7. Reinstall the spark plug.
8. Rotate the piston to bottom dead center (BDC) and
9. Slowly pull the recoil starter handle until resistance is felt. Leave it
in that position.
10. Clean the engine thoroughly with an oiled cloth.
NOTE: If POLARIS fuel system additive is not used, the fuel tank, fuel lines,
and carburetor should be completely drained of gasoline. Observe all
fire safety rules when draining the carburetor. Review the fuel-related
warnings on page 43. To eliminate any fuel remaining in the carbure-
tor, run the engine until it stops.
