Morning all!

I have a question about the above carb. Have a friend with an issue that is causing some issues. On his rebuild he got a 32/36 5200 from Tom L and its been draining the entire bowl after you shut off the truck. About 30 seconds after turning off the key raw fuel just pours out of the secondary and goes till the bowl has about 1/16" of fuel in the bottom. The floats appear to be set correctly and the fuel level is not pouring over as you can see the top of the bowl from the top of the carb because its open to atmosphere. We removed the carb yesterday and placed it over a container with 2 rods supporting it from the bottom. We removed the top half and poured fuel into the bowl. If we fill the bowl slowly nothing happens till we hit approx 3/4" full and the fuel just starts to pour out of the secondary. Its leaving thru 2 small holes located just below the secondary plate. The unit will continue to steadily dip till the bowl is almost 100% empty. It looks like it stops just at the lower edge of the main jets in the bowl.

It seems like we hit a level in the bowl that cause it to start to drain and it continues to drain due to a siphon effect.
