What is the advantage of carburetor in fuel system?

Carbureted systems are simple: less parts, less complexity, less maintenance. In fact, our carbureted Cessnas do not need fuel pumps since the fuel tanks are high (in the wings) and push the fuel all the way to the carburetor. One thing carbureted engines do need is carb heat.
