A round disc mounted on a shaft located at the intake end of the carburetor is called a:

Choke
Float
Throttle
Venturi

The correct answer is: Choke

The correct answer is "Choke." In a carburetor, the choke is a round disc mounted on a shaft at the intake end. The choke is responsible for restricting the flow of air into the engine to create a richer fuel mixture when starting a cold engine. This richer mixture helps the engine start more easily by providing more fuel for combustion. The other options are not correct: - Float: The float in a carburetor is a mechanism that controls the fuel level within the carburetor bowl. - Throttle: The throttle controls the amount of air and fuel mixture entering the engine. - Venturi: The venturi is a constricted section in the carburetor that creates a low-pressure area to draw fuel into the airstream.
