CONTROLS
1. Fuel Valve
The fuel valve opens and closes the passage between the fuel tank and the carburetor.
The fuel valve must be in the ON position for the engine to run. When the engine is not
in use, be sure the fuel valve is in the OFF position to prevent carburetor ooding and
to reduce the possibility of fuel leakage.
2. Engine ON/OFF Switch (per engine specification)
The engine switch enables and disables the ignition system. Turn the engine switch to
the ON position to start the engine. Turn the engine switch to the OFF position to stop
the engine.
3. Choke Lever
The choke lever opens and closes the choke valve in the carburetor. The “ON” position
enriches the fuel mixture which makes it easier when starting a cold engine. The
opposite position provides the correct fuel mixture for operation after engine warms up.
4. Throttle Lever (per engine specification)
The throttle lever controls engine speed (RPMs). Moving the throttle lever in the
directions shown makes the engine run faster or slower. (Non-generator applications.)
5. Recoil Starter Grip
Pulling the starter grip operates the recoil starter to crank the engine. Always grip snugly
and have your body positioned properly when pulling. Keep thumb on the end of the
handle in case of kick-back.

HIGH ALTITUDE OPERATION
Carburetor Modifications
The standard carburetor air-fuel mixture may be too rich when operated at high altitude
resulting in possible decreased performance and increased fuel consumption. Please
have an authorized LCT Service Center modify this engine’s carburetor if it is operated
continuously above 5000 feet. Failure to modify may result in poor engine performance,
spark plug fouling, hard starting, and increased emissions.
Carburetor modication by an authorized LCT Service Center will improve performance
and allow this engine to continually meet US EPA and California ARB emission
standards throughout its useful life.
Important Note
When the carburetor has been modied for high altitude operation, the air-fuel mixture
may be too lean for operation at 5000 feet or below. This could result in the engine
overheating and could cause serious engine damage. Please have an authorized LCT
Service Center restore high altitude converted carburetors back to the original factory
specication before operating below 5000 feet.
