instructions)

allow it to enter the fuel system.
4. Shut off engine
5. Disconnect spark plug wire and remove spark plug
6. Add one teaspoon oil through spark plug hole
7. Place rag over spark plug hole and turn starter (or pull the
recoil) a few times to lubricate the combustion chamber.
8. Replace spark plug, but do not reconnect the spark plug
wire.
