Answer
Hello Bill:

Sorry for the Delay. This Question was Located in the Question Pool. Change the Plug. If the New Plug Does Not Fire, then the Coil/Ign Module is Bad or a Safety Switch is Bad. Remove the Spark Plug. Wrap a Wire Around the Threads and Attach the Other End of the Wire to the Engine Block Turn the Engine and See if the Plug Fires. If No, then Disconnect the Shut Off Wire  at the Control Bracket First, Check for Fire at the Plug. If Still No Fire at the Plug; Then Disconnect the Shut Off Wire at the Coil (usually requires removal of the blower housing) and Check for Fire at the Plug. If No Fire at the Plug , then the Coil/Ign Module is Bad. The Coil/Ign Module to Flywheel Gap is .020in. If the Plug Fires at Anytime During these 2 Checks, then a Safety Switch or Wire May be the Problem. Yes the Engine will Turn Even with a Bad Safety Switch. The Blade Safety is Usually the Cause of this. The Starter Turns and The Engine Doesn't Fire is an Indication of a Bad Coil/Ign Module or a Faulty Blade Safety Switch. The Clutch Safety Prevents the Starter from Engaging so the Mower Does Not Move when the Starter Turns the Engine. The Seat Safety is Designed to Stop the Engine if the Blades are Engaged or the Clutch Safety is Not Engaged when you Leave the Seat. Usually if the Engine will Run for 15 to 20 Minutes and Quits and the Plug is Not Firing Immediately After the Engine Quits, then the Coil/Ign Module is Bad and Requires Replacing. If the Plug is Firing Immediately After, then Usually the Gas Flow to the carburetor is Being Restricted bt a Blockage at the Gas Tank. Check the Tank for Trash/Water and Check the Gas Tanks Cap and Ensure it is Venting the Tank Properly. If it is Not Venting the Tank a Vaccum will Build and Restrict the Gas Flow to the Carburetor. From your Description, it Sounds like the Coil/Ign Module is Bad. Hope this Helps. I am Here if You Require More Assistance. Let me Know What Happens, Please. Thanks.

Good Luck
