Small Engines (Lawn Mowers, etc.): john deere l110 engine problem, john deere l110, kohler command

Question
I HAVE A JOHN DEERE L110 WITH KOHLER COMMAND 17.5 ENGINE. I REPLACED THE SPARK PLUG AND FUEL FILTER AND THE ENGINE STARTS, RUNS FOR ABOUT A MINUTE, SPUTTERS AND SHUTS OFF. IT WILL REALLY ONLY STAY RUNNING FOR THE MINUTE IF LEFT IN CHOKE POSITION.

Common Causes:

Check for water in the fuel tank, hoses and fuel bowl on the carb. If water is found, be sure to check your fuel can as well!
Check for a major air leak from around the intake or carb mounting area. If the carb is equipped with a built in primer bulb, check it closely for any major air leakage.
If this problem occurs only during cold starts, you may also have a situation where the choke or primer is not working properly.
Finally, don't forget to check the fuel cap to make sure it's venting properly. A cap that doesn't vent properly, will not allow fuel to flow from the tank to the carb.
