Plugs all uniformly black idles fairly smooth plugs and wires new somehow seems carb dumping to much gas
Possibly due to misfiring? Have you checked ignition components? I would pull the spark plugs and see if waht they look like, especially differences between cylinders.

This valve is designed to cut off the fuel flow into the carb if the fuel level in the chamber reaches a certain level, pushing the float up and closing the valve. However, if the valve has gunk in it, it won't close fully, so the pressure from the fuel pump will force fuel past the valve and up & out of the jet.
Take this valve out (Once again, carefully...) and either give it a good wash out, or replace it...
