Though they are easier to start, carbureted engines are less efficient during flight. Since the fuel/air mixture in carbureted systems meet at the carburetor, the mixture is less precise for each cylinder. Fuel injectors are calibrated to force the same amount of fuel into each cylinder. Because of their precision, most fuel injection systems also permit monitoring of each cylinder’s EGT (Exhaust Gas Temperature). EGT probes on each cylinder allow the pilot to create the ideal engine performance; saving fuel, as well as reducing wear on the engine. For these reasons, as well as many others, fuel injected engines are standard on most new aircraft.
Don’t forget the possibility of carb icing. Not saying I wouldn’t take one but I’d exhaust all FI resources before I bought a carburetor.
