Fuel System Components

The typical carbureted fuel system and related

components include the following:

• Fuel Tank and Valve

• Fuel Lines

• In-line Fuel Filter

• Fuel Pump

• Carburetor

Operation

The fuel from the tank is moved through the in-line

equipped with a fuel pump, the fuel tank outlet is

located above the carburetor inlet allowing gravity to

feed fuel to the carburetor.

drawn into the carburetor body. There, the fuel is

mixed with air. This fuel-air mixture is then burned in

the engine combustion chamber.

Fuel Recommendations

General Recommendations

Purchase gasoline in small quantities that can be used

within 30 days and store only in clean, approved

(see Storage in Section 1), to minimize gum deposits

and ensure easy starting. Do not use gasoline

containing Methanol, or add oil to the gasoline.

to expand.

Fuel Type

For best results, use only clean, fresh, unleaded

gasoline with a pump sticker octane rating of 87 or

higher. In countries using the Research fuel rating

method, it should be 90 octane minimum.

Unleaded gasoline is recommended as it leaves

less combustion chamber deposits and reduces

harmful exhaust emissions. Leaded gasoline is not

recommended.

Gasoline/Alcohol blends

Gasohol (up to 10% ethyl alcohol, 90% unleaded

gasoline by volume) is approved as a fuel for Kohler
