How to Check and Adjust the Spark Plug’s Gap

One of the most important things you can do to keep your Lawn Mower running smoothly is to check and adjust the Spark Plug’s Gap. The Spark Plug’s Gap is the distance between the two electrodes on the spark plug. It is important to make sure that this gap is set correctly because if it is not, it can cause problems with the engine.

The correct gap for a spark plug depends on the type of spark plug and the engine it is installed in. You can usually find the recommended gap size in the owner’s manual for your Lawn Mower. If you are not sure what the correct gap size is, you can find it online or by contacting the manufacturer.

To adjust the Spark Plug’s Gap, you will need a spark plug wrench and a feeler gauge. The spark plug wrench is used to remove the spark plugs, and the feeler gauge is used to measure the gap.

First, use the spark plug wrench to remove the spark plugs from your Lawn Mower. Then, use the feeler gauge to measure the gap between the two electrodes on each of the plugs. If the gap is not set correctly, you can use the screwdriver on the side of the wrench to adjust it. Be sure to tighten the screws firmly, but do not over-tighten them or you may damage the spark plug.

Once all of the Spark Plugs have been adjusted, re-insert them into the engine and tighten them in place with the wrench. Then, start the engine and check to make sure that there is a spark at each plug.
