Choke Knob; Shift Lever - Honda HS624 Owner's Manual

CONTROLS & FEATURES
Choke Knob (HS1132 Only)
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.
Shift Lever
The shift lever selects F (FORWARD), N (NEUTRAL), or R (REVERSE).
The shift lever also controls the transmission drive ratio; moving the lever
farther from NEUTRAL increases drive speed. While clearing snow, use the
shift lever to control drive speed, so you can leave the throttle lever in the FAST
position for best snow-clearing performance.
