What does a fuel solenoid do on a riding lawn mower?
The anti-afterfire solenoid is a device that shuts OFF the fuel at the carburetor to prevent the engine from receiving fuel after the ignition switch is shut OFF. Anti-after fire solenoids are installed on select engines that have a battery-powered electrical system.
What causes an engine to hunt and surge?
If an engine is not getting enough fuel (this is called “running lean”), due to fuel pressure (regulated by the fuel pump and regulator), restricted fuel injectors, a vacuum leak or really anything that throws off the fuel mixture going in to the engine, this can cause the surge.

What can cause a carburetor to flood?
