John Deere LT 155

[chasteen1]

Mower runs for approx 30 min and then will shut off and only run with full choke. If it cools it will again run. New ignition module, clean carb and good fuel pump. Just got it back from the dealer after all belts were replaced. Any Help is greatly appreciated.
Thanks
Steve

Check the fuel cap, loosen it, if it run better check the vent hole in the cap.
It has been a problem for a while starting with the L series. They just need to be cleaned periodically I keep a small piece of wire handy near the fuel cans poke into the vent when fueling no more problems.
