GB Remanufacturing, Inc. began operations in 1986. The company, founded by William Kitching and his son Michael Kitching, remains family owned and operated. The company’s first product line was choke pull-offs and was offered to carburetor remanufacturers and part suppliers. GB expanded its product line to include throttle position sensors, mixture control solenoids, and other carburetor components based on customer feedback and demand.
