Control Functions - Benchmark BP Series Manual

2.2 CONTROL FUNCTIONS

Fuel Valve Lever
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, leave the fuel valve lever in the
OFF position to prevent carburetor ooding and to reduce the possibility
of fuel leakage.
Choke Lever
The choke lever opens and closes the choke valve in the carburetor. The
CHOKE (closed) position enriches the fuel mixture for starting a cold
engine. The RUN (open) position provides the correct fuel mixture for
operation after starting, and for restarting a warm engine.
