Setting Engine Speed - Honda GCV520 Owner's Manual

SETTING ENGINE SPEED

Position the throttle lever for the desired engine speed.
Some engine applications use a remotely-mounted throttle control
rather than the engine-mounted throttle lever shown here.
For engine speed recommendations, refer to the instructions provided
with the equipment powered by this engine.
Do not disconnect the battery from the engine while the engine is
running. Disconnecting the battery causes the fuel-cut solenoid to shut
off the flow of fuel to the carburetor main jet, and the engine will stop.
