Why is my lawn mower spark plug wet?
Electrodes that have been worn thin are a sign of overheating, often caused by too much ethanol in the gas. If your plug has wet, oily deposits, it's time to take the mower in for servicing, because oil is leaking into the combustion chamber where it shouldn't be.
Also, 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.
Accordingly, what do you do when your spark plug gets wet?
A wet spark plug can be the result of the engine flooding. Flooding is what happens when you try to start the engine several times without it firing up. You can clean the spark plugs or you can just wait for them to dry out.
