What Happens If I Use The Wrong Spark Plug In My Lawn Mower?

Your chainsaw or lawn mower’s engine’s performance may be affected by the spark plug you use. This is because, for a spark plug to function correctly, it must adhere to a precise set of requirements. Even while all spark plugs are nominally made to fulfill the same function, some significant variations can affect how well an engine runs.

An engine that runs poorly or a fire may result from using the incorrect spark plug in a lawn mower. A few things can happen when you put the wrong spark plug in a lawn mower. First, it’s possible for the engine to misfire, which would run unevenly and risk damage to your mower if the piston head contacts the end of the spark plug.

One of the most common is that mowers have engines built a certain way, so adding the wrong spark plug and starting your mower engine could be impossible. The engine may also shut off because of an overheated spark plug. Using the wrong spark plug might lead to expensive repairs or mower replacement in either scenario.

Use the chart for the Husqvarna lawn mower spark plug size, so no issues occur. (Read Where Is Husqvarna Made)

What To Do If You Used The Wrong Spark Plug?

You can try a few things to fix the problem if you think you used the wrong spark plug. But first, if you think you may have used the wrong spark plug, follow these steps:

  1. To begin with, check to be sure the engine is firing correctly. You might need to replace the spark plug if it isn’t.
  2. If the engine is still not firing correctly, you can check for ignition system problems or misfires.
  3. Use the right tool to remove the plug from the engine.
  4. Check the gap between the electrodes using a feeler gauge. (Feeler gauges are a small set of tools that fit between two surfaces to measure small gaps using varying thicknesses of metal.
  5. Change to another spark plug if it’s too wide or too small. Your engine might not start if the gap is too small or too wide as it can’t complete making a spark.
  6. Make sure the electrode is installed correctly and is clean.
