Draining my carb

Hey gang,

Silly question to ask… My Sportsman 2013 500HO has been sitting all winter due the amount of snow we received here in New Hampshire. I wanted to drain the carb before I start it up to get rid of the old gas in the carb. Question is, how do I drain the carb? Is there a screw on the side of the carb or do I have to remove the bolt on the bottom of the carb (which I cannot get a box end wrench on)? Thanks guys!!
