My engine quits running when hot. I can only start it on

Customer Question

My engine quits running when hot. I can only start it on full choke and to get back to the barn, i must run the engine slowly. It is on a hustler super Z mower. Took it in for service and they cleaned the carburetor. After an hour of operation it began to quit again. What's up with that?

The fuel solenoid in the carburetor may be shutting down. It has to stay open, or it plugs the main jet. Has t have 12 volts to stay open. Best test is to remove it and plug the hole for test.
