463 no shut down

[gtruck]

I've got a 2001 463. The ignition key starts the machine but wont stop the engine. I replaced the ign switch and same thing. I'm suspecting the fuel is not being cut off which prob means a bad solenoid? Anybody have this problem? thanks

My 453 did that once and I found one of the wires going to the shut down timer/relay had corroded and broke off. See these threads.

If its like the bigger kubota engines there's a spring that pulls back the fuel shut off when the solenoid is released, you could try cleaning out the solenoid and the boot on it.

On the little Kubota's in the 453/463 machines the solenoid is energized when you turn off the key. The timer/relay shuts the fuel off for a short period of time and then releases.
