Island Automotion rebuilds the famous SU (Skinner's Union) carburetors found on so many favourite classic cars, including the MG series like the MGA and MGB and MGC, and Triumphs like the TR-4 and Spitfire. Jaguar, Rolls Royce, Bentley, and the more esoteric makes like Alvis also used this quintessentially British carburetor. Manufacturers like Volvo used SU carbs for years, and no 122S model can sound or perform correctly without a pair of HS6's on it. We overhaul, rebuild, refurbish, restore, repair – call it what you will – the great SU carburetor.
In the 1960's the Zenith Stromberg carburetor was developed, in two basic sizes, the CD150 and the CD175. These carbs were designed with the same principles in mind, but they were achieved with a slightly different execution. Of course in the early days of the SU carburetor, George and Carl Skinner used a leather bellows which deflected upwards with increasing airflow and decreasing pressure, and it could be argued that this design preceded the hydrin diaphragm of the Stromberg by many years. We rebuild and service the Stromberg carburetor as well, to the same high standards as an SU.
