See full version: What does it mean when water comes out of the spark plug hole
If you are getting water on electrode end you have a blown head gasket. This means removing the head and replacing the head gasket. If you are getting water on the outside of your spark plug or plugs you have a water leak somewhere.
No, it’s a bad idea. WD-40 isn’t a great lubricant, it’s mostly a solvent and it will tend to wash oil off the cylinder walls which is absolutely not what you want to do before starting an engine. more
For the optimal functioning of your lawn mower, the spark plug has to be in good condition – which means it must not be wet. If you notice that it is wet, you can take various steps to correct the problem, or you can choose to replace the plug itself so that it does not lead to lasting system damage.
The answer is always going to be NO! more
However, before knowing if the plug should be wet, it is good to know why a spark plug exists and what it does.
Having a lawn mower is great, but it can be frustrating when it fails to work as expected. While there are many reasons your lawn mower may stop working, one of the more common issues may be with your spark plug.
Another way is examining the carburetor throat. If you place some drops of fresh fuel, start it up, and notice that the engine runs out the fresh gas, then you likely have an issue of blockage or bad gas. here
When examining the electrode, you should have a flat top. Anything other than that, such as a rounded top, and the spark plug needs a replacement. In addition, make sure to check for signs of physical damage to the porcelain sheath, such as chips or cracks, and pitting on the firing electrode. [links]
The aim here is making sure there are no traces of leakage or dirt on the spark plug – otherwise, the operation of the system will be interfered with. If there is any damage that you did not notice due to the presence of the residue, then you should replace the spark plug.

If you are having issues with starting your mower – it could ver well be your spark plug and we are going to give you some things you should be looking at.

In a small engine such as a lawnmower, a spark plug is important because it gives a pathway for ignition to occur which is what helps the engine to start. It is an electric gadget that fits into the cylinder head of the engine and helps the engine to kick-start the combustion process when you switch it on.
It’s a good idea that if you are going to be replacing your fuel injectors that you replace them all at the same time. Otherwise, you could have some fuel injectors that are working great and some that aren’t working well which can cause your engine to run unevenly and vibrate. here
Now as you may or may not know there are multiple parts to your EGR system of your car, not just one piece. That’s why OBD2 codes can be helpful but usually are not that descriptive.
Your mass airflow sensor or O2 sensor is designed to be able to measure how much air is coming in through your engine air filter and being delivered to the engine. If your mass airflow sensor is not able to accurately measure how much air is flowing through the air intake it will adjust the engine mapping for the worst possible conditions. This can ultimately cause your spark plugs to end up black and wet as your engine may be pumping more fuel into the cylinder to compensate for the lack of air coming in. [links]
If your spark plugs are old and have carbon buildup on them they may not be able to fully burn the air and fuel mixture in the combustion chamber, this can lead your spark plugs to end up black and wet over time. If you are unsure of the last time your spark plugs were replaced it would be a good idea to go ahead and replace them at this time, especially if they are currently black and wet.
If your fuel injectors are cracked or damaged they can cause more fuel to be injected into your engine cylinders that may not fully be burnt off during the combustion process that will cause your spark plugs to turn black and wet over time. more
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. here
When the gas pours into the cylinders, if the car does not start the spark plugs can get wet. If the spark plugs are wet it is impossible for them to spark, which prevents the car from starting. This is referred to as flooding.
How do you fix a wet spark plug? [links]
Furthermore, should a spark plug be wet or dry?
The fix for wet spark plugs (assuming there are no underlying ignition coil, plug wire or crank sensor problems) if often just to wait and try starting the engine again later. Spraying some starting fluid (ether) into the throttle body and cranking the engine may get the fire going and dry the plugs. more
