Question
My generator had been sitting for a while with the same gas in a garage. So drained the old gas replaced with new gas and it starts right up, runs for about 10 min until warm/hot then shuts down. What are your suggestions, and yes I'm handy so i can change the filters (oil and gas) etc. Really need to get this thing going ASAP. Any help you can give will be much appreciated. Thank You in advance

Hello Andre:

The Running Time is the Key to Locating the Cause of the Problem.  Check the Gas Tank Cap and Make Sure it is Venting the Tank Properly. If the Cap is Venting the Tank, then Run the Engine Until it Quits, then 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 The Following is an Instruction File I Made for Checking and Repairing this Problem. 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. On Some Model JD Engines, there is a Igniter that Goes Bad and Not the Coil. The Igniter is the Same as an Ignition Module. 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. Check the Tank for Trash/Grit/Water. Clean the Tank if Necessary. If you Hit a Snag or this Does Not Correct the Problem,  I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Thanks.

Good Luck
