Section 5. Fuel System And Governor - Kohler CH11-16 Service Manual

Fuel System and Governor
Description
WARNING: Explosive Fuel!
Gasoline is extremely flammable and its vapors can explode
if ignited. Store gasoline only in approved containers, in
well ventilated, unoccupied buildings, away from sparks or
flames. Do not fill the fuel tank while the engine is hot or
running, since spilled fuel could ignite if it comes in contact
with hot parts or sparks from ignition. Do not start the
engine near spilled fuel. Never use gasoline as a cleaning
agent.
Fuel System Components
The typical fuel system and related components
include the following:
• Fuel Tank • Fuel Lines
• In-Line Fuel Filter • Fuel Pump
• Carburetor
Operation
The fuel from the tank is moved through the in-line
filter and fuel lines by the fuel pump. On engines not
equipped with a fuel pump, the fuel tank outlet is
located above the carburetor inlet; gravity moves the
fuel.
Fuel then enters the carburetor float bowl and is
moved into the carburetor body. There, the fuel is
mixed with air. This fuel-air mixture is then burned
in the engine combustion chamber.
Section 5
Fuel Filter
Most engines are equipped with an in-line fuel filter.
Periodically inspect the filter and replace with a
genuine Kohler filter every 200 operating hours.
Fuel Line
In compliance with CARB Tier III Emission
Regulations, these engines with a Family
identification number beginning with 6 or greater
(see Figure 5-1), must use Low Permeation SAE 30 R7
rated fuel line; certified to meet CARB requirements.
Standard fuel line may not be used. Order
replacement hose by part number through a Kohler
Engine Service Dealer.
