Fog the Engine
1. Treat the fuel system with Polaris Carbon Clean. See page 107.
2. Support the front end of the machine so the engine is level or tilted
slightly rearward.
3. Remove the spark plug. Pour 2-3 tablespoons (30-40 ml) of engine
oil into the hole.
Tip: Use a section of small hose and a small plastic squeeze bottle filled with the
pre-measured amount of oil.
4. Reinstall the spark plug. Torque to specification.
5. Apply dielectric grease to the inside of the spark plug cap. Reinstall
the cap.
6. Turn the engine over several times using the electric start. Oil will
be forced in and around the piston rings and ring lands, coating the
cylinder with a protective film of fresh oil.
7. If Polaris fuel system additive is not used, the fuel tank, fuel lines,
and carburetor should be completely drained of gasoline.
8. To eliminate any fuel remaining in the carburetor, run the engine
until it stops.
