Why is my lawn mower spark plug wet?

Also know, what does a wet spark plug mean?
A wet spark plug likely means that it hasn't been firing due to engine flooding or a bad ignition cable. Dirt or moisture on the outside of the spark plug that provides a conductive path to ground, or an internal crack in the spark plug's ceramic insulator that shorts the plug to ground also can be the culprit.
