Okay, now do the same with Pierburg variable venturi carburetor such as one found in old Saab 900 engines. That thing is pretty nice because it doesn't need a choke to run run cold and since the venturi dimensions change according to throttle the fuel is mixed very well on all throttle levels. And there's no electronics or other external controls of any kind - it all works with vacuum from the carburetor. The genious part is having a oil dampener to allows the user to rapidly change the throttle position without the engine stalling because the venturi change speed is limited by the oil dampener. And you could tweak the dampening both by changing the amount of oil or the viscosity of oil in the dampener to tune it perfectly.
