12. Storage Instruction
In the event your kart is not to be operated for periods in excess of 30 days or at the
end of each driving season prepare for storage as follows:
12.1. Drain fuel tank by allowing engine to run out of fuel, or use a fuel stabilizer.
12.2. Lubricate engine cylinder by removing the spark plug and pour one ounce of clean
lubricating oil through the spark plug hole into the cylinder. Crank the engine slowly
to spread oil and replace spark plug.
12.3. Do not save or store gasoline over winter. Using old gasoline, which has
deteriorated from storage, will cause hard starting and affect engine performance.
Do not drain fuel while engine is hot. Be sure to move Off high way recreational
vehicle outside before draining fuel
