Abstract
A carburetor float bowl is provided which is elongated in a direction lengthwise of the vehicle and has a smooth upwardly curved section on the bottom wall at the front and rear ends of the float bowl to minimize sloshing of the gasoline and also minimize foaming of the gasoline within the float bowl during severe back and forth rocking movement of the carburetor as would occur in a motorcycle passing over a series of bumps at a high speed.
