Small Engines (Lawn Mowers, etc.): mower stalls, question pool, kohler command

Question
Hi. I have a Scott's riding mower with a Kohler command 16 engine on it. The mower starts and runs fine for about 45 minutes then it seems to "run out of gas" even though the tank is plenty full. When you inspect the fuel filter you can see that there is no longer any fuel in it. To resolve the problem I remove the fuel line coming from the tank to the filter and the fuel flows no problem. I then reconnect the line, you see fuel flow into the filter, the engine starts right up and youare on your way but this time only for about 20 minutes until the cycle begins again. I've changed the fuel filter, the air filter, the oil and filter, the spark plug, the gas cap, and nothing seems to have resolved the issue. Any help would be greatly appreciated as I have vowed not to go through another cutting season with the channel locks in my pocket ready to spring into action. Thanks.

Answer
Hello Ted:

>>Sorry for the Delay. This Question was Located in the Question Pool and I can Only Answer Questions from the Question Pool when I am Not Answering Questions here or at the Other Site I Answer Questions at.
>>From your Description it Sounds like the Carburetor Solenoid is Heating up and Requires Replacing or 1 of the causes Listed in the File I am Including.
>>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 () 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
