This may not be that helpfull to too many, but it will be usefull for me and thought I would pass it on.
I came up with it trying to figure out a way to use a spare petcock I have for a service tank. That way I can do the true float height check and not deal with the tank while syncronizing the carbs. I got a tank off an old lawnmower and it only has the space to mount one petcock. So, I wanted a way to have both the nipples of the petcock flow at once and still be able to turn it off.
I think I will also use it on my tank and only deal with one petcock.
If you swap the L and R handles from one side to the other, you get a whole new funtion. I made a diagram to illustrate...
