Answer
Hello Chris:

>>Did you Soak the Carburetor in Cleaning Solution?
>>If No, then
>>The Carburetor can Still be the cause for this Problem.
>>Send me the Model and Type or Spec Numbers Off the Engine and the Unit/Mower Model Numbers, Please. With these I can Locate the Proper Manual and Better Assist you. The Engine Model Numbers May be Stamped Into the Blower Housing (metal engine cover) Above the Spark Plug. The Unit/Mower Model Numbers are Usually Located Under the Seat on a Sticker on the Body of the Mower.
1- >>The Following is a Simple Way to make Sure the Engine is Getting Gas from the Carburetor to Run.
>>Remove the Fuel Line from the Carburetor and make sure there is Gas coming from the Tank to the Carburetor. If the Gas is Flowing, then
>>Pour a Small Amount of Gas (approximately 1/4oz) into the Carburetor Throat and Try to Start the Engine.
>>If the Engine Starts and Quits, then Check the Carburetor Solenoid.
>>If the Carburetor Solenoid is Good or has been Removed and the Engine will Start and Quit when the Gas is Poured into the Carburetor Throat, then Soak and Clean the Carburetor.
2- >>The Following is a Basic Instruction File I Made for Checking the Coil/Ign Coil/Magnetron/Armature on Small Engines. Any Input is Appreciated.
1- >>If the Unit Runs and Quits after 5 Minutes to 3/4 Hrs and will Restart after the Unit Cools (sometimes as little as 30min), then
>>Check for Spark as Soon as the Engine Quits.
>>Have a Good Plug with a Wire Around it Ready and when the Unit Quits Running, Remove the Plug Wire and Attach it to the Standby Plug. Check for Fire.
>> ***Be Careful, The Engine and Plug are Hot and I Suggest you Wear Gloves.***
>>If the Plug is Firing , then
>>Remove the Spark Plug from the Engine and USE IT to Check for Fire.
>>Sometimes a Spark Plug can have a Problem with Not Firing when Hot.
2- >>**To Check the Ign Coil if the Engine is Not Starting and Running at All; Remove the Spark Plug/s.
>>With a Good Plug, Wrap a Wire Around the Threads of the Plug and Attach the Other End of the Wire to the Engine Block.
>>Check for Fire at the Plug. If No Fire, then
>>Remove the Blower Housing (metal engine cover).
>>The Wire that is Connected to the Coil/Ign Module from the Shut Off Switch needs to be Removed (unplugged) from the Coil/Ign Module.
>>Now Check for Spark at the Plug.
>>If Spark, then the Shut Off Switch or the Wire is Bad.
>>If Still No Spark, then the Coil/Ign Module is Bad. If there are Safety Switches on this Unit and the Coil is Good; you Need to Check the Safety Switches for Being Bad and Check the Oil Guard Switch also.**  
>>The Following is an Instruction File for the Safety Switch System. Any Input is Appreciated.
>>The Color Code of the Wires May be Different than those I Use as a Reference in the Instruction File.
>>**PLEASE REMEMBER THAT THE INSTRUCTIONS FOR CHECKING THE SAFETY SWITCHES IS JUST THAT!!! FOR CHECKING ONLY.
>>I NEVER Suggest a Mower be Operated with a Safety Device or Switch Disconnected or Bypassed.
>>**Now. On Some Model Mowers you can Simply Unplug the Safety Switch from the Harness. On Other Models you have to Place a Jumper Wire Between the Harness Terminals (on the 4 Post Switch (Clutch/Brake) Jumper from Same Color Wire (Example: White to White) First and then Check for Fire, Now Include the Black to Black Wires if No Fire. Check the Clutch/Brake and the Blade/PTO Safety Switches First.  Then Check the Oil Guard Switch (if Applicable). Check the Seat Safety Last. Usually the Seat Safety is Not in the System for Starting the Engine. Just to Ensure Someone is in the Seat when Engaging the Transaxle and/or Blades. Use a Paper Clip or a Short Wire to Make a Jumper.**  
>>Use a Multi-meter and Check the Continuity of the Switch. The Meter should Show when the Contacts are Closed and Open. The Meter will Swing All the Way Over when the Switch Contacts are Closed and Swing Back to the Rest Point when the Switch Contacts are Open.
>>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
