B112 leaking gas from carb



I know I have seen this numerous times but cannot seem to find it searching.

I know these old carbs are prone to draining their fuel tanks straight through the carburetor at times and believe there is a small o-ring that can be added to help seal it off and prevent this.

Can anyone point me to the information on what to get and where to install it on the carb?  

One of my B112's is so bad it just starts running straight out right after I open the inline shutoff.  I am going to pull and clean the carb, try to ensure the float is adjusted and the needle seating correctly but anything I can do to help prevent future leaks would be appreciated.
