Fuel in the bowl

Converting over to electric fuel pump on the carb should allow me be driving along, cut the fuel pump off and do a time/speed comparison from the time the fuel is switched off until the engine sputters indicating it has consumed the 200 or so ml of fuel in the bowls.
I don't know how much volume the fuel bowl holds but I can find out next time I pull the carb. It just needs to be consistently full when I turn it off.
The way the fuel floats are it should give a very stable fuel level in the bowl.

I could also use it to cut evaporative emissions. Once I learn how far it goes on a bowl full of fuel I can turn off the fuel, keep driving that last little bit home and could pull into the drive way with an empty or almost carb.
Usually the engine heat conducts up into to the fuel and off gasses the lighter components of gasoline to the surrounding environment.
It could make cold weather starting easier too, when I start it flip the fuel pump on several seconds before cranking and get a bowl full of nice fresh volatile gasoline.

Has anyone tried this?
