Carburetor Identification

Carburetor can be identified by tag attached to carburetor by one air horn screw. Ford Motor Co. tags include prefix and suffix of part number. Jeep Corp. tags include entire part number. Tag must remain with carburetor at all times to insure proper identification.

Model 4300 carburetors are of three-piece body design with a single fuel bowl for all barrels. Primary system has throttle lever stop screw for idle speed adjustment, and may have either a dashpot or throttle positioner solenoid incorporated. Secondary system has spring-loaded air valves located above secondary throttle valves. On model 4300-A carburetors, an integral hydraulic dashpot dampens sudden movement of air valve plates to aid in preventing flutter and erratic engine operation. On model 4300-D carburetors, secondary fuel supply is controlled by metering rods attached to air valve plates. Secondary throttle valves are mechanically operated by primary throttle linkage.
