For one thing it sounds like you have some extremely flooded plugs that will need replacing before it starts. And you had best change the oil and filter first too because it sounds like you have alot of fuel gotten into the oil. I would also squirt some oil into the spark plug holes before trying to start it again because of washed cylinders. It also sounds like a stuck needle and seat. the carb flooding over started while running the last time & the reason for the rough running.
