There should be a small screw in the bottom of the bowl on the side of a little spig (hose ) connection. You push a small hose on to it then put other end in a container and open the screw ( the screw does not need to be totally removed it should start draining after a couple of turns) and if that does not work you will have to take carb. off and remove the bowl. If you are going that far then you might as well clean the carb well it is out.
Hope this helps.
snug them don't tighten them
Without an air vent the fuel would not flow to the carb.
on the left(shifter side) of the carb, on the float bowl. small standard screw (flat head)
Near the kick stand. The bolt is horizontal.
You're running way rich. Adjust your carb's mixture screws.
The carb bowl drain nut is located on the bottom of the carb.

There will be a screw at the bottom of the carb. You loosen it and what ever fuel is in that carb will come out. Just be sure to try to catch it in something. You will get several ounces of fuel that come out.
That hose is the drain. It can just end somewhere safe, below the motor and out of the way.
What I've always done is put the gas tank on reserve and pull the hose that connects from the tank to the carb and have it drain into a gas can. It will get almost all the gas out of the tank.
