Welcome to Outdoorking, acawse. I suggest you go through the basic process, to get reasonably reliable data. First, remove the spark plug, clamp its metal body to a cylinder head fin, reconnect the lead, put the speed control in the starting position, and pull the starter. Check the even-ness and blue colour of the string of sparks. If you pass that test, turn off the fuel, pull it over a few times without the spark plug to clear the crankcase of fuel, squirt a spoonful of fuel into the spark plug hole, put the plug back in and connect it, put the speed control in the starting position and pull it over (leaving the fuel turned off). Check for it starting and running for a short time.
If that approach shows that it has spark, and will fire with the correct amount of fuel, the main question is whether you have a carburetor fault or an air leak into the crankcase. The wet plug suggests you may have a flooding problem, and it hasn't been starting because it has a crankcase full of fuel.
Please give us an update after checking these things.
