Speed governors are typically located near the engine or motor. They are often mounted on the engine's intake manifold or carburetor, or on the motor's electrical control panel. Some speed governors are also built into the engine or motor itself.
The appearance of a speed governor will vary depending on the type of machine it is installed on. However, most speed governors are small, compact devices that are made of metal or plastic. They typically have a lever or knob that can be used to adjust the speed of the engine or motor.
