Where does the air into the carburetor comes from? For a naturally aspirated system,air will pass to the air filter and goes into the carburetor, but then what governs the velocity of the air?

The pistons in the engine will try and pull their displacement causing a vacuum to form in the air intake manifold, which will pull vacuum at the bottom of the carburetor. A venturi tube inside the carburetor forces the air to speed up as it passes through. The size of the venturi, the displacement of the engine, the number of cylinders, all contribute to the velocity of the air flowing through the carburetor.

The throttle plate controls how much air goes in. The throttle plate is at the bottom of the carburetor.
