QuestionMy gx95 lawn mower wont start.When i test for spark I'm removing the plug,reinstalling the wire to the plug and turning over the engine. the plug sparks only when i place it next to the block or any other metal part of the engine.Is that correct? The air filter is old.was'nt sure if i was getting enough air so i removed the filter to ensure air flow.still O.K.? Fuel, not sure how to test if it's getting fuel. It has a Kawasaki engine not sure what size. 12.5hp. Also read mention of a spark plug ground strap.Dont know what that is or if i have or need one.
Thanks Wayne
AnswerHello Wayne:
>>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.
>>That is Correct.
>>The Spark Plug "MUST BE GROUNDED" to the Engine or the Frame to Fire.
>>I am Including the File for Coil Testing in Case you Require it in the Future.
>>I am Also Including the File for Checking the Carburetor since the Spark Plug is Firing.
>>The Following is a Basic Instruction File I made for Checking a No Plug Fire Situation on JD Mowers.
>>To Check the Coil, Remove the Blower Housing (metal Engine Cover) and Disconnect the Cut Off Wire from the Coil.
>>Remove the Spark Plug/s and Wrap a Wire Around the Threaded Area of the Plug/s. Attach the Other End of the Wire to the Engine Block. Turn the Engine Over and Watch for Fire at the Plug/s.
>>If you have Fire, then a Safety Switch is Bad of there is a Ground in the Wiring Harness. If No Fire at the Plugs, then the Ign Coil is Bad and Requires Replacing.

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.
>>To Check the Safety Switches; 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 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. 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.**
>>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.
