If the plug is wet like you say then the saw is flooded.   

What I do is pull the plug and blow it off with some compressed air.   Then with the plug out pull the engine over a couple of times with the starter rope.   Then blow down the spark plug hole with compressed air and look for a spray from fuel.   Do this procedure, starter rope then compressed air until you see no more spray coming from the spark plug hole. 

Put the plug back in and put the choke in run mode and hold the throttle wide open and see if it will start.

If not pull the plug again and see if it is wet.  If it is then the needle in the carb could be stuck open and you need to rebuild the carb or you have no spark.
