* Airflow: Air enters from the top of the carburetor and flows down through the venturi, creating a vacuum that draws fuel from the bowl.
* Advantages: Better fuel distribution, less prone to icing, easier to tune.
* Disadvantages: More complex design, higher cost.
* Commonly found in: Older American cars, some European vehicles.
2. Up-Draft Carburetor:
* Airflow: Air enters from the bottom of the carburetor and flows upwards through the venturi, creating a vacuum that draws fuel from the bowl.
* Advantages: Simpler design, lower cost.
* Disadvantages: Prone to icing, fuel distribution can be uneven, less efficient.
* Commonly found in: Older trucks, industrial engines.
Note: While these are the most common types, other variations exist, like side-draft and progressive carburetors.
