Kohler Courage 149cc mower is winning. Need Advice

I have a Craftsman Push Mower, with Kohler 149cc engine, it sat for two years and wouldnt start. I changed the oil, cleaned the carburetor, put new fuel in, and it ran fine. A week later, i went to start it, and it will not start at all. I pulled the carburetor again, cleaned it multiple times. I also changed the spark plug, changed the fuel again, and it still will not start.
I changed the spark plug because when i pulled it the first time, it was wet.
I am at a loss at what to attempt next. Does anyone have any suggestions or advice for me? It sounds like it wants to start, but just will not.

Thanks!
