What does a fuel solenoid do on a riding lawnmower?

A fuel solenoid on a riding lawnmower is an electromechanical device that controls the flow of fuel to the engine. When the ignition is turned on, the solenoid activates, opening a valve that allows fuel to flow from the tank to the carburetor. This ensures that the engine receives the proper fuel supply for starting and running. If the solenoid fails, the mower may experience starting issues or run poorly due to inadequate fuel delivery.
