My Z425 starts but stops after running a few seconds. Seems like it is not getting fuel but all seems ok. Any ideas?

What have you done?
What have you checked for?
Check for spark Bad ignition module/coil(s)
Check for fuel (fuel filter, fuel pump, then carb (float, inlet valve, jets, idle circcuit,) if equipped, or plugged injectors

Not all "ok" if it stops running after a few seconds, maybe check if it is still getting fuel.. If not, why.. fuel filter, bad fuel, ??

If getting fuel, then go to shutoff conditions.. safety switch, ??

Well I changed the fuel filter, changed the plugs and that's about it so far. Changed the solenoid last year. It starts up and then after about 5 to 10 seconds it just quits. Got me confused.

Do you use the choke ? mine must be choked on cold starts.

Check the fuel shutoff solenoid. It may be bound up, not opening all the way.

Yes. I have to use the choke every time I start it. always had since I owned the mower.

Is the fuel solenoid easily found or do I have to dis-assemble the sheet metal to get to it.

Fuel solenoid is part of the carb, usually attached/part of the fuel bowl.
