   Probably because carurators are a lot more effective than most people
think. One major advantage of the comperized system is that it should not
degrade over time the way that a mechanical carburator does. In addition,
an electronic system with it's feedback system can adjust for a wider range
of conditions than a carburator can. The one area where an electronic
system is much more effective than a carburator is in cold starting. In a
cold engine, a lot of the fuel puddles on the metal surfaces causing wasted
fuel and high hydro-carbon emmissions. Direct fuel injection in to the
combustion chamber alleviates a lot of that.
