Typical carbureted fuel system and related components
include:
● Fuel tank.
● Fuel line.
● In-line fuel lter.
● Fuel tank lter (in-nipple).
● Fuel shut-off valve (if equipped).
● Carburetor.
Fuel tank outlet is located above carburetor inlet,
allowing gravity to feed fuel through in-line lter and fuel
line to carburetor.
Fuel enters carburetor through fuel shut-off valve and
sediment bowl and then goes to carburetor oat bowl.
Fuel is drawn into carburetor body and mixed with air.
This fuel-air mixture is then burned in engine combustion
chamber.
FUEL RECOMMENDATIONS
Refer to Maintenance.
FUEL LINE
Low permeation fuel line must be installed on carbureted
Kohler Co. engines to maintain EPA and CARB
regulatory compliance.
FUEL SHUT-OFF (if equipped)
Some engines are equipped with a fuel shut-off located
at carburetor. It controls fuel ow from tank to carburetor.
