ABSTRACT:
The carburetor has a principal fuel jetting system which is situated upstream of a principal throttle member actuated by the operator and, for cold starting, an auxiliary starting device, controlled by the engine temperature, to increase the flow-rate of fuel and if necessary the flow-rate of air admitted into the intake pipe of the engine with respect to the flow-rate corresponding to hot idling. The starting device comprises a closure valve means adapted, as long as the engine has not reached its normal operating temperature, to open a channel which receives a mixture of air and of fuel in a well-determined proportion and which opens into the zone of the intake pipe situated downstream of its principal throttle member. A starting valve situated in the intake pipe upstream of the principal jetting system, is maintained sufficiently open, when the engine is warm, not to substantially enrich the air/fuel mixture on idling and at very small engine loads.
