How to Remove Spark Plug from Lawn Mower-Step by Step

What you will need:

  • Extension Wire (Ratchet will be useful too)
  • Spark Plug
  • An assistant
  • New Spark Plug
  • Multimeter (optional but recommended)

Step: 1. Make sure your lawn mower is turned off and that it’s not running. Also, make sure to remove the old spark plug properly. Do not use any tools or anything else that can damage it because this will be important for getting the lawn mower started again.

Step: 2. Find out where your spark plug wire is located. It’s best to do this by visually inspecting it because there are often multiple wires that can come from different places. You need to find out which one is your spark plug wire because the other ones are for other components on your lawn mower.

Step: 3. Once you have found the right wire, disconnect it using your ratchet or an extension wire. Make sure to stand somewhere safe when doing this because there may be sparks flying out of your lawn mower.

Step: 4. Now that the spark plug wire is disconnected, everything else should fall into place easily. Your goal now is to take off the old spark plug by unscrewing it. You can do this by hand or with a ratchet.

Step: 5. After unscrewing the old spark plug, replace it with the new one and screw it back in. It’s always best to use the same spark plug type for your lawn mower so that everything works properly again.

Step: 6. If you have a multimeter, you can use it to test the new spark plug. This is an optional step, but it will tell you if your lawn mower has started working again or not.

If you put the red screen of the multimeter on top of the spark plug’s end and then pull that off with your hands, there should be enough power for a small spark to come out. If that is not happening, your lawn mower will not work again.

Step: 7. After everything is done, all you have to do now is put the new spark plug wire back onto its original place and connect it. Make sure to do this securely so that sparks don’t fly.

Step: 8. Now, you can go ahead and start your lawn mower again to see if it works properly. If everything is done right, your lawn mower should turn on just fine after this repair. Good luck.

Signs Your Spark Plug Needs Changing

There are a few signs that can indicate that your spark plug needs changing:

1. Trouble Starting Up

If your lawn mower is difficult to start up, then this could be a sign of a faulty spark plug. There’s a chance that the gap between the piston and the wire on the spark plug is small and needs replacing.

2. Engine Dies Quickly

Another sign is if your lawn mower dies quickly when using it. This might be because the spark plug wire has worn out over time which causes the power to stop flowing through it.

You can fix this by replacing your spark plugs with new ones, and then everything should work fine again.

5. Foul Smell Comes Out of the Engine

If there is a really bad smell coming out of the engine that smells like gas, then it could be because your spark plug wire is faulty.
