KVH, I went through the gas overflow several times. It was always a stuck float valve. The fuel only has one way in, and one way to stop flow. That's the float valve. Setting the height of the floats is critical as you've seen, yet the problem for me was debris getting into the float valve between the needle and body, thus allowing a flooding condition. I've since installed a glass filter just before the carbs and haven't had a flooding issue since.
 
I discovered yesterday that my fuel pump is pushing just over 1 psi and when rest, loses all back pressure instantly. So I now have my starvation problem solved I hope
 
I’m curious. How old is the pump? Same style as new ones from Moss?

I just checked mine. 2.4 pounds. Takes at least a few minutes to relieve built -up pressure.
