Here are three general designs of carburetors:
A. Downdraft Carburetor: Air flows downwards through the carburetor into the engine. This is the most common design in modern (carbureted) vehicles due to gravity assisting fuel flow and better fuel atomization.
B. Updraft Carburetor: Air flows upwards through the carburetor. This design was common in older engines and some industrial applications, but it can struggle with fuel delivery against gravity.
C. Side-draft (or Horizontal-draft) Carburetor: Air flows horizontally through the carburetor. This design is often used where vertical space is limited, such as in some sports cars or motorcycles.
