2000 big bear gas leak?
 

Thanks for your time if your reading this. I am new here.
I have a 2000 yamaha big bear 350, this atv runs like new. (Recently bought) I parked it in my garage and could smell gas everytime I was in there. I had just cleaned the carb so I figured it was from that, still very strong odor. Then I loaded it on my truck and underneath where it was parked was a puddle of gas about a foot in diameter. I am not a mechanic but it seems to be coming out of what I think is an overflow hose off the carb. That hose looks like it should be connected to something cause there's a 90 degree bend at the end of it.
Is this normal for the gas to be leaking? I'm guessing no. Any help would be awesome. Thank you
