Abstract
A device for controlling an acceleration pump for a carburetor includes a positioning member, a stopper and an actuating means. The positioning member is preferably formed integrally with a piston slidably set in the acceleration pump. The stopper is arranged to move in a direction perpendicular to a sliding direction of the piston. According to the positions of the stopper, the positioning member engages the stopper at a plurality of predetermined positions so that the stroke of the piston may change. The actuating means may be bellows or others. The bellows contains therein an air pressure equal to the standard air pressure at a low place whereby the bellows can expand at a high place due to the air pressure difference. In addition, the actuating means can be controlled in response to the ambient temperature.
