Abstract
In a four-barrel carburetor, a pair of plain tube primary mixture conduits each has a main well receiving fuel through a main jet controlled by a metering rod which is positioned by a vacuum responsive piston. An auxiliary fuel passage receives fuel both through an auxiliary jet controlled by a metering rod positioned by a vacuum responsive piston and through a supplementary jet controlled by a metering rod positioned by an ambient pressure responsive bellows. A pair of transfer passages respectively connect the auxiliary fuel passage to the main wells.
