Yes that is what I was thinking.
For testing time or distance with the fuel in the bowl I would hold the gas in the same position as to not add more fuel with the accelerator pump.
Then for fuel burn off I figure I would be pushing the petal down a little here and there just driving normally and maybe more as it ran out of fuel, draining the accelerator cylinder. I figure it would get 50% to 90% of the gas out of the bowls. And therefor cut evap 50% to 90%.
When the carb starts to heat up it starts off gassing through all the little vents, I can see the refraction of light through the gas, looks like a little propane leak.
