Very interesting. Shows why carburetors evolved to the point they are, and things that have to be taken into consideration, like fuel and air inertia, fuel atomization and lack of when the throttle is wide open, and reversion. The difference in atomization was very noticeable between almost closed throttle and wide open. The amount of fuel that continued to come out of the jet after the throttle was closed (due to inertia) was surprising.
