Fuel Valve Lever
The fuel valve opens and closes the passage
between the fuel tank and the carburetor. The fuel
valve lever must be in the ON position for the
engine to run. When the engine is not in use, leave
the fuel valve lever in the OFF position to prevent
carburetor flooding and to reduce the possibility of
fuel leakage.
Throttle Lever
The throttle lever controls engine speed. Moving
the throttle lever in the directions (shown below)
makes the engine run faster or slower.
Engine Switch
The engine switch enables and disables the ignition
system. The engine switch must be in the ON posi-
tion for the engine to run. Turning the engine switch
to the OFF position stops the engine.
Choke Lever
The choke lever opens and closes the choke valve
in the carburetor. The CLOSE position enriches the
fuel mixture for starting a cold engine. The OPEN
position provides the correct fuel mixture for opera-
tion after starting and for restarting a warm engine.
Some engine applications use a remotely-mounted
choke control rather than the engine-mounted
choke lever shown here.
Recoil Starter Grip
Pulling the starter grip operates the recoil starter to
crank the engine.
