As long as you can pressurize a separate container, like a burette, you can precisely measure the amount of fuel consumed.
A small hand pump to pressurize the burette will provide the same fuel pressure as long as you maintain the pressure within specs.
Fill the burette, pump the pressure up to the maximum specs recommended and maintain the pressure with the hand pump. This way you can test anything you want without dealing with float chamber variations that would affect the main circuit operation.
Want a lower float chamber level for lean burn? Let the pump pressure in your burette drop off below the minimum spec and the fuel level in the chamber will drop and you can control that very precisely.
As far as the evaporation you saw when rejetting, ASSuming it was a hot engine, most of the fuel evaporation was due to the heat produced by the engine. Try it over a hot engine, then a cold engine to confirm my statement.
