What Happens If You Use the Wrong Spark Plug in a Lawn Mower?
The type of spark plug used in your mower or chainsaw’s engine plays a significant role in its performance. Each spark plug has specific requirements that must be met for optimal functionality.
In other words, while all spark plugs are designed to serve the same purpose, there are key differences between them that can influence how an engine performs. Using an incorrect spark plug in a lawn mower might result in poor engine performance or, worse, a fire.
If the wrong spark plug is used, several issues can arise. For one, the engine may misfire, causing it to run unevenly and potentially damaging the mower. Alternatively, the spark plug could overheat, causing the engine to shut down.
In either scenario, using the wrong spark plug might necessitate costly repairs or even a complete replacement of the lawn mower.
To avoid such problems, you must follow proper guidelines when selecting a spark plug. By adhering to these recommendations, you can ensure your lawn mower operates efficiently and safely.
What To Do If You Used the Wrong Spark Plug?
If you think you’ve used the wrong spark plug, there are a few things you can do to try and fix the problem.
- First, check to see if the engine is firing correctly. If it isn’t, you may need to replace the spark plug.
- If the engine continues to struggle after this initial effort, it may be worthwhile to investigate potential misfires or issues within the ignition system.
- Check the gap between the electrodes using a feeler gauge.
- If the gap is too wide or too small, switch to a different spark plug.
- Make sure the electrode is clean and properly installed.
