JD JX75 won't stay running

jdgt225innh(z5 NH)August 24, 2008

I've got a John Deere JX75 mower that's about 5 years old. I'ts got a Kawasaki 6.75 hp engine. It's been running great ever since it was new, except for yesterday. I lifted it up to put on a couple saw horses to change the blade from standard to mulch. I put it back on the ground, serviced the fuel tank, and started it up. As soon as I take it off choke it quits. It will only run with the choke on, and it runs fine with the choke on. I know the blade swap has nothing to do with this problem, but what could it be? The owners manual says nothing about a fuel filter. Any ideas?

Was the mower tipped at all? Does it have a shut off valve on this model? If no and no, drain or remove the carb bowl and see if any water / debris are present.

I tipped it a bit when taking it on and off of the saw horses. I didn't realize it had a shut-off. I suppose it's for safety? Anyway, just for the heck of it when I started it up today, I tipped it in the opposite direction. Much to my relief it started running normally again. Is this normal with this mower? Or is there something in the fuel control failng?

Sorry tomplum, after I reread your post I realized you were asking me if it had a fuel shut-off, not telling me. No, it does not have a manual shut-off. Perhaps I should drop the carb bowl because it sounds like there may be debris like you said. Especially if there are changes in the running condition when tipped from one side to the other.

Sounds like water in the fuel tank.

jx 75 starts in choke mode and runs for only about 2 seconds, was running fine all day then died and now only runs for a couple of seconds. Any idea?? thanks
