Question -
I have a Deere GT-245 which is two years old & has been maintained well.Has just over 100 hrs.Always seemed to run rich-smoked & lacked power.Has the 20 HP Kawasaki engine.Quit while running & have not been able to get it running since with the exception of one time when a friend & I shut off the fuel line to the carb & fed gas from a lab squeeze bottle to air horn.It ran perfectly this way.Have thoroughly cleaned the carb, replaced carb, replaced fuel pump, replaced plugs to no avail.Liquid fuel accumulates in the air horn while trying to crank.Obviously too rich to crank.I am more accustomed to not enough fuel-what is going on here?Thanks in advance!!!

 Hello Toby:

 This Engine came with 4 Different Style of Carburators and Manifolds. It Could be Several things. 1- the Float Level is Too High and Allowing the Carburator to Flood or the Float Needle isnt Seating Properly. 2- the Air Mixture Screws are Set too Rich. 3- the Soleniod in the Bowl is Bad. Hope this Helps. Let me know what Happens, Please. I enjoy knowing the Outcome. Thanks.
John, One thing I did while I had the carb off for cleaning was to check the float action & seating of the needle.That worked fine.I see no adjustment for float level nor adjustments for air mixture.Deere confirmed that float was not adjustable.Solenoid in bowl has been changed also & according to Deere it shuts off fuel to carb when key is off.
 Good Luck

 Respectfully

 Hello Toby:

 I know the Soleniod Shuts Off the Gas when the Key is Turned Off, but they have a Tendancy to go Bad and Allow Gas into the Carburator when the Key is Off. I have had Instances where they have Caused the Float to Stick at the Bottom of the Bowl and allow the Carburator to Flood Also. Go to this Addy http://jdpc.deere.com/jdpc/servlet/com.deere.u90490.partscatalog.view.servlets.H and Enter the Model Numbers GT245 and Click Search. Then Click on the Model in the Search Results. Then Click on Sectional Index. From here you can View the Breakdown of Each Section of the Mower. Try Adjusting the Screw (diagram #25) in the Bowl. This Screw has a Spring Around the Threads. Turn it In 1/4 Turn and see if it Leans out the Carburator. Hope this Helps. Let me know what Happens, Please. I enjoy knowing the Outcome. Thanks.

 Good Luck
