DON'T EVEN THINK ABOUT REBUILDING ANOTHER ROCHESTER FOUR BARREL QUADRAJET CARBURETOR without installing the Barker Bushing Kit and using the Barker Un-Warping Tool to un-warp the fuel float assembly and air horn sections, and repair the factory defects, including all the soft plugs. We also can rebuild your Rochester Quadrajet carburetors, and repair all the defects. To assist, we have on line instructions for installing the Barker Bushing Kit, where the technician can view the easy service procedure.
These instructions have been prepared to assist the technician in the correct techniques of installing the Barker Bushing Kit in the Q-Jet base plates.
The purpose of installing this bushing kit is to eliminate the vacuum leaks at the throttle shaft, and to increase engine response. However if the carburetor has other problems you may not notice the benefit of the bushing kit, so additional repairs maybe needed such as the fuel and air assemblies should possibly be un-warped.
