I was surprised with the level of uncertainty in this thread.

Liquid fuel does not burn. It has to be vapor to burn. New cars are all about low emissions. Our favorite classic mopars had high emissions because carburetors while good at making power are not so good at low emissions. If a carburetor could atomize fuel as well as fuel injection - new cars would sport carbs.

The smaller the fuel droplet the more surface area for evaporation. Carbs drip the fuel, fuel injection sprays in a fine mist. The mist has more surface area resulting in better mixture with the air. Fuel injection is also constantly "jetting" the injectors. Making small adjustments in pulse width for any throttle position or engine load. A graph of the oxygen sensor signal on a properly running engine will cycle just above and just below stoichiometry. If the oxygen sensor signal spends too much time rich or lean it flags a code. If the fuel trims get too far rich or lean they flag a code. Carburetors are good but they are never as good as injection.

Carbs always run rich - especially on choke. That extra fuel is what wore out old engines. It washed the oil off the cylinders causing the ring ridge. It then ended up in the oil pan diluting the oil wearing out the bearings. Modern engines are barely broke in at 100,000 miles. It's because of the fuel injection mixing the air/fuel well enough that after combustion minimal fuel is left over.
