Question

What statement is correct realating to a fuel level check of a float-type carburetor?

a- the low-pressure area created in the throat of the venturi pulls the fuel from the idel passage
b- Climatic conditions have very little effect on idle mixture requirements
c- The low pressure between the edges of the throttle valve and the throttle body pulls the fuel from the idle passage

Answer 1

The correct statement relating to a fuel level check of a float-type carburetor is that the low pressure between the edges of the throttle valve and the throttle body pulls the fuel from the idle passage.

Step-by-step explanation:

Of the statements provided about a fuel level check of a float-type carburetor, the correct one is: The low pressure between the edges of the throttle valve and the throttle body pulls the fuel from the idle passage.

When the throttle valve is in the closed position, a low-pressure area is created between the edges of the throttle valve and the throttle body. This low pressure pulls fuel from the idle passage, allowing the engine to idle smoothly. As the throttle valve opens, the low-pressure area decreases and the fuel flow is adjusted accordingly.
