Simply so, do lawn mower spark plugs need to be gapped?
Depending on the type of spark plug needed for your lawnmower engine, the gap between the post and tongue (center and ground electrodes) must be set a specific width. If the gap is too large, the spark generated in the center electrode will not travel completely to the ground electrode.
- You can't get the engine to fire up at all.
- You have to tug extra hard for longer than usual on the rewind.
- Your lawn mower loses power while moving.
- The gas runs out quicker than it used to.
In this manner, what will happen if the spark plug gap is wrong?
If the spark plug gap is incorrectly set, it can lead to engine issues. The customer may experience loss of power, misfires, spark plug fouling, increased plug wear, or poor gas mileage.
