Starting Pull Start Engines - Generac Power Systems GP Series Owner's Manual

Operation
• Use regular UNLEADED gasoline with the generator engine. Do
not use premium gasoline. Do not mix oil with gasoline.
• Clean area around fuel fill cap, remove cap.
• Slowly add unleaded regular gasoline to fuel tank. Fill to bottom
of screen filter. Be careful not to overfill (Figure 11).
• Install fuel cap and wipe up any spilled gasoline.
IMPORTANT: It is important to prevent gum deposits from forming
in fuel system parts such as the carburetor, fuel hose or tank
during storage. Alcohol-blended fuels (called gasohol, ethanol
or methanol) can attract moisture, which leads to separation and
formation of acids during storage. Acidic gas can damage the fuel
system of an engine while in storage. To avoid engine problems,
the fuel system should be emptied before storage of 30 days or
longer. See the "Storage" section. Never use engine or carburetor
cleaner products in the fuel tank as permanent damage may occur.
