Small Engines (Lawn Mowers, etc.): JD LT133 stalls out when hot, john deere lt133, hose clamps

Question
Please bear with me as I know very little about engine repair. I have a John Deere LT133 with a 13hp Kohler engine.  I just purchased it and the first time I tried to cut with it it ran for about 20 mins and stalled out and wouldn't restart.  I was able to get it started a few days later but it would only run at full choke.  When I opened the throttle it would stall.  Several days later I was able to mow with it for about 20 mins and had the same problem.  I removed the engine shroud and cleaned a nest of some sort from around the cooling fins????(not sure thats what they are called), but the problem still persists.  Any help would be greatly appreciated.  Thanks,  Jeff

Answer
Hello Jeff:

>>No Worries.
>>You can View a Breakdown/IPL of the Engine and Mower at this Site Addy, http://jdpc.deere.com/jdpc/servlet/com.deere.u90490.partscatalog.view.servlets.H... and Enter the Model Numbers LT133 and Click Find. Then Select your Model from the Search Results Area. Then Select the Sectional File. Then Select the Section of the Mower you Wish to View Online. *You can Drag the View Windows for Better Viewing.*
>>The Following is a Basic Instruction File I made for this. Any Input is Appreciated. I Usually Suggest you Check the Following in this Order for a Problem like yours.
>>1- Check the Gas Tank Cap and Ensure it is Venting the Tank. A Vacuum Builds in the Tank and the Gas Flow Stops or Slows (15 to 45 Minutes and if the Small Granular Sand is in the Tank it can Take Several Days of Constant Running to Bring All the Sand Particles to the Tank Outlet Port) to a Point it Shuts Off the Engine.
>>2- Operate the Equipment Until it Quits (15min to 1hr). Then Immediately Check for Fire from the Plug. If the Plug is Firing, then
>>3- Replace All the Spring Style Hose Clamps with Screw Style Hose Clamps on the Fuel System.
>>4- Check the Carburetor Solenoid. If the Carburetor Shut Off Solenoid has Current, then Remove the Carburetor Solenoid and Go to the Hardware Store. Purchase a Bolt of the Same Diameter and Threads. It Needs to be 3/4" Long. Put this Bolt in Place of the Solenoid. If this Corrects the Engine Problem, then Replace the Solenoid. ***NOTE: THIS IS FOR CHECKING THE SOLENOID ONLY I NEVER SUGGEST YOU OPERATE THE ENGINE WITH THE SOLENOID OUT OF THE CARBURETOR EXCEPT FOR TESTING PURPOSES*** Sometimes the Plunger is Moving, Just Not Far Enough to Allow the Gas to Enter the Jets.
>>5- Depending on the Model Mower, it can Also be the Pickup Tube in the Gas Tank.
>>If No Fire, then Remove the Shut Off Wire from the Coil and Check for Fire.
>>If Still No Fire, then the Ign Module or Coil is Bad. **Even if the Coil is New or Fairly New, it can Still be Bad.** On JD Mowers; Remove the Igniter/Module and the Coil and have the Local JD Dealer Test them.
>>If you Hit a Snag or this Does Not Correct the Problem,  I Hope to be Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.

Good Luck
