Welcome to Carbdoctor.com. I specialize in Rochester Quadrajet, Tri Power, and just about any type of Automotive carburetors.  I've been rebuilding carbs since 1964 and have done thousands.  I was a quality control engineer for many years in well known Carburetor rebuilding shops including contracts with AC Delco.  Cars are my life. I still collect, drive and race whenever I can.
