What carburetor component limits the maximum airflow into the engine at full throttle?

Throttle valve
Venturi
Main metering jet
Air filter

The correct answer is: Venturi

The venturi is a constriction in the carburetor bore that creates a low-pressure area to increase the velocity of air flow. This increase in velocity draws fuel from the main metering jet, providing the correct fuel-to-air ratio for optimal engine performance at full throttle. The throttle valve, although important for regulating air flow, does not limit the maximum airflow at full throttle. The main metering jet and air filter also do not limit airflow - they are responsible for delivering fuel and filtering air, respectively.
