Preset Gap (in) is 0.028 Inch. Other than having to reset the gap to .040 for my Kohler CV15S. It works great.
It Sparks Like a Spark Plug
What can one say about a spark plug? It sparks and allows my Craftsman lawn mower to run. I don't know about its longevity; I haven't had it long enough. However, since the lawn mower manufacturer recommends changing the spark plug once a year; I will buy the cheapest one available next year.
