There has been arguments over the advantages and disadvantage of carburetors when weighed against engines with fuel injection. It’s true that both have their merits and demerits. However, a great deal hangs on what you actually like in an engine. Both have much to offer and can give great service.
An engine with a carburetor comes around five times less than one with fuel injection which demands for a very large savings. However, the maintenance rate of a carburetor engine are generally higher than for one with fuel injection so it can all even out at the end of the day.
Even fuel injection prices may vary greatly. Direct fuel injection, in particular, seems to be much higher in cost than common port fuel injection.

Emissions are a important factors in modern motoring and is likely to be even more critical in the future. This is where fuel injection has many merits. Carburetor engines were fine when little premium was ever paid to the amount of CO2 being emitted but these days, the restrictions on car emissions means that more and more manufacturers will be leaning toward fuel injection for their cars.
Again, the nod for fuel economy points to fuel injection. The way a carburetor is set up means that to obtain truly excellent fuel economy, you’d constantly have to be tinkering with the settings to allow for variations in weather and atmosphere and this isn’t really practical. As gas prices go up, carburetor engines are becoming less and less sought after.
If power and performance are the main criteria in your choice of engine, you be on the side of carburetors. This is because a carburetor engine has no limit on the amount of gas that can be pumped from the tank. This means that cam modifications will allow more fuel come through the carburetor and into the cylinders. This results in a denser mixture in the chamber and higher levels of power.
The only means to try and rival this with fuel injection is by turbo-charging or super-charging to get the same kind of flexibility. For normal daily driving, however, extra power doesn’t really seem a big deal. Extra power is always going to result in greater gas consumption which, in turn, will lead to greater costs.
A carburetor is very complex and has to be adjusted properly in order to work efficiently. By contrast, a fuel injection setup is extremely simple. A carburetor depends on a float and needs to regulate the amount of fuel passing through to the engine. With a carburetor engine, one cylinder will get more fuel than another cylinder. In a fuel injection engine, each cylinder receives the same amount of fuel. In this particular area, there’s little that can be done to improve the design of the carburetor.
With fuel injection systems, the fuel passes through a line under pressure to the fuel injectors. The car’s computer instructs each injector on when it should open and at this point, the fuel enters the cylinders. As it runs through the cylinder, fuel becomes atomized so it burns more effectively
