What is the correct spark plug gap for lawn mowers?
Setting the Gap on Your Spark Plug
You'll need a spark plug gauge to adjust the gap on your lawn mower's spark plug. Although many small engine spark plugs require a .030 gap, this varies depending on the engine type. You can check this on the engine owners manual.

Similarly, 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.
What happens if you put the wrong spark plug in your lawn mower?
Spark plugs that are gapped incorrectly can cause an engine to miss, or run erratically, especially during idle. The incorrect spark plug gaps can cause uneven firing of individual spark plugs and delay engine combustion; both of which can cause an engine to miss or idle erratically.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.Husqvarna 455 Chainsaw Review
