Choke Knob - Honda GX610 Owner's Manual

CONTROLS & FEATURES
Choke Knob
The choke knob opens and closes the choke valve in the carburetor.
The CLOSED position enriches the fuel mixture for starting a cold engine.
The OPEN position provides the correct fuel mixture for operation after
starting, and for restarting a warm engine.
Some engine applications use a remotely-mounted choke control rather than
the engine-mounted choke knob shown here.
