There is an o ring that holds the float asembly. I have had the o ring fail twice. There is only 2 screws the hold the bowl on. I had to replace the gasket to stop another leak. The whole garage smelled like gas when that was leaking. Get the rebuild kit and change all the o rings and gaskets. This is on a 2011 scrambler. This had been the worst carb from leaking that I have ever had. I also have had a lot of trouble with the battery. When I bought the scrambler the battery was dead at the dealer they replaced the battery but gave me the original too. Even the new battery would be dead if it sat a week. So I switched back to original after charging. Worked fine but a week later it was dead again. So I ended up taking a battery out of my sled and put in it to try another one. It was a larger battery and a gel battery. Problem solved. I know it sounds like there was a draw on the battery but then the problem would has still been there with the gel battery. There is plenty of room in the battery box for a larger battery. Now I just swap the battery back and forth between the scrambler and my mxz 600.
