What This Carburetor Float Does
The carburetor float works together with the needle and seat assembly to control fuel level inside the carburetor bowl.
Maintaining correct fuel level helps provide proper idle quality, throttle response, fuel delivery, and reliable engine operation.

Replacing worn carburetor floats during carburetor service helps restore proper fuel system operation.
