9.  Replace the spark plug.
10.  Move the generator to a clean, dry place for storage.

5.  With the fuel shut off valve open, start the engine 

and allow the generator to run until all the remaining 

gasoline in the fuel lines and carburetor is consumed 

and the engine shuts off. 

6.  Close the fuel shut off valve.
7.  Change the oil.
8.  Remove the spark plug and place about 1 

tablespoon of oil in the spark plug opening. While 

placing a clean rag over the spark plug opening, 

slowly pull there coil handle to allow the engine to 

turn over several times. This will distribute the oil 

and protect the cylinder wall from corroding during 

storage.
