Running rich, check your jets, (carburetor) make sure your float is free.
Yes but, wet with what ?
blown head gasket??
That strongly implies that the plug or plugs are not firing at all.
Probably losing spark in that one cylinder, maybe a faulty spark plug, a spark plug wire or distributor cap.
Your lawn mower spark plug may be wet due to excess fuel in the engine or a faulty carburetor. To fix it, you can try cleaning or replacing the spark plug, adjusting the carburetor, or checking for any fuel leaks in the system.
water ha ha ha
Try starting the engine, pull the spark plug out and see if it is wet with gas, if it is you might not have any spark(possible from a fouled spark plug) or it might have low compression, put the plug into the spark plug boot and set the tip of the plug onto something that is metal on the engine and turn the engine over. you should see spark, no spark=ignition problem. If the plug is not wet the engine isn't getting any gas and you have a carburetor problem.
It is important to address a wet spark plug in a lawn mower because it can prevent the engine from starting or running properly. To fix it effectively, you can remove the spark plug, dry it off, clean any excess fuel, and then reinstall it.
Cracked distributor cap or bad spark plug wires/connections.
Possible causes, mixed up spark plug wires, wet/damp spark plug wires, a bad distributor cap and/or rotor and a burned intake valve could cause the 4.3 to pop through the throttle body.
Fouling spark plugs can happen when the tip temperature is insufficient to burn off carbon, fuel, oil or other deposits and causes spark to leach to metal shell...no spark across plug gap will cause a misfire. Wet-fouled spark plugs must be changed as they won't fire. Dry-fouled spark plugs can sometimes be successfully cleaned by bringing the engine up to the operating temp.
well the real question is do you have spark are you getting fuel? well you can take and roll the motor oveer and then pull the spark plug. if the spark plug is wet you don't have spark if the spark plug is dry you have spark that's the easiest way to take a look. the motor need three thing to run fuel oxygen and spark. DO NOT ROLL THE MOTOR OVER WITH THE SPARK PLUG OUT OF THE CYLINDER YOU WILL MORE THAN LIKELY LIGHT THE FUEL THATS PUSHED OUT OF THE MOTOR IN THE COMPRESSION STAGE. when you find out if the motors getting fuel and not spark it could be your crank sensor which tells the motor when to ignite the spark plug to cause your explosion which makes the motor run. i hope this was helpful.
