HI, I have a 18 hp Husqvarna YTH1848XP with the 18 HP Kawasaki. It is like 13 years old and has almost 600 hr on it. Today I was cutting around the shed and it was running just fine. When I got done and headed for the shed to put it away it died as if I had just turned off the key. I checked for spark and there is plenty of that. Any of you have another place should I should look? Tomorrow I will check fuel delivery but it was cutting heavy grass just before it plucked. I think there is some sort of carb shut off thing on the bowel of the carb. Could that be it and how would you test it?
Thanks for any advice in advance.
Kev.

Many "modern" engines have a vacuum fuel valve.

Start with a shot of fuel down the carb, if the engine starts and dies, you have a delivery issue.

Runs with fuel shot down the intake so it has to be fuel, Pump seems to be working fine. I am thinking it has to do with that solenoid with that wire that is in the bowel. Is that some kind of shut off thing?
Tks, Kev

I removed the shut-off solenoid from the carb, checked it and it does not work, I ground down the needle shaft on the solenoid replaced it into the carb and installed a shut-off valve in the fuel line. Works just fine
