Abstract
A carburetor for an internal combustion engine has an auxiliary starting device for delivering fuel and air to the induction passage during starting and cold running. The starting device comprises a duct opening into the induction passage downstream of the throttle means receiving fuel and air, and provided with a closure valve opened until the temperature of the engine has reached a first predetermined value. The flow of fuel entering the duct is reduced upon the engine becoming self operative. A flap located in the induction passage upstream of the opening of the main fuel delivery system is biased toward opening by the air flow around it and is resiliently biased toward closure with a force which decreases as the temperature of the engine increases.
