Dennis Barker builds Hot Rods, Muscle Cars, and he designed the first electric Jeep Top for Wranglers out of a four bay automotive customizing shop in Basalt, near Aspen, Colorado. It is also at the Barker Gang Garage that Dennis invented the first Rochester Quadrajet Carburetor Un-warping Tool, and the Barker Throttle Shaft Bushing Kit. After years of frustration, mechanics and other automotive industry professionals are now able to solve the vacuum leak issues associated with the Quadrajet Carburetor. This new technology does improve emission test results, and the overall performance, and will make carburetor rebuilding easier, and much more reliable.

At the SEMA show more than 250 Distributors signed up to market both these new products. "The hunger for parts and techniques to improve the defects in the Quadrajet Carburetor, which resulted in years of rebuilding problems has skyrocketed,” noted Dennis Barker, President of Barker Gang Garage. “That prompted us to offer a line of Rochester carburetor parts and tools that we have been using during the past 25 years for those who enjoy wrenching on their cars as much as driving them when the Quadrajet is working right. Simply put, all Quadrajets are warped and have loose throttle shafts, and the only chance of repairing them to work correctly is by using these new parts and tools.”

Mario Sturde, Market Development Manager for Barker Gang Garage, explains how it works, “Once a straight edge is held between the front two bolt holes on the air horn and float bowl surfaces of a Rochester Quadrajet Carburetor, the warpage is easily seen. Also a warped Quadrajet that’s mounted to an intake manifold is usually 200% more warped than when removed, due to the front two bolts applying additional pressure. Once the Quadrajet Carburetor has gone through our un-warping process, it is almost impossible to warp it again, allowing the front two bolts to be tightened upon re-installation of the carburetor to the intake manifold without the worry of warping the carburetor again.” Barkers’ five pack Bushing Kit supplies enough bushings and screws to rebuild 5 Rochester Carburetors. When these bushings are used in conjunction with the Barker Un-warping Tool, vacuum leaks and emissions will dramatically decrease, while overall performance is noticeably improved. Tests prove that the Rochester Quadrajet Carburetor works better than new when the unwarping tool and bushing kits are used during the carburetor rebuilding process.
