Island Automotion

Island Automotion Ltd. is on the web at From Alvis to Volvo, Triumph to Jaguar, Rolls-Royce, Bentley, and Healey, Island Automotion has complete and extensive experience with SU carburetors. Stock rebuilds, custom rebuilds, and specialty applications can all be entrusted to Island Automotion.

Experience here is not derived just from just carburetor work, but from forty years of working on nearly every aspect of vintage cars. Now I rebuild carburetors, returning them to the condition they were in when the cars were new. Achieving that is done through proper and complete mechanical restoration, and at Island Automotion that means using only SU original equipment replacement parts, and skillful and accurate machining. Your engine doesn’t care what the carburetor looks like – only that it meters fuel and air correctly. Appearance, although important, is secondary. The engine must run properly.

So if you require professional rebuilding of SU or Stromberg carburetors, you’ve come to the right place. You have my word on that.

Specialty Fabrication Services

Here is a triple set of Rover HD8 carbs on a Jaguar 3.8 E-type manifold. As received the set was in very poor condition and the linkage was not working smoothly. Most troubling was the fuel manifold, made hastily to serve the three Rover carbs whose fuel inlets are arranged differently. I re-configured the linkage, rebuilt the carbs, and proposed fabricating a new fuel manifold. Consequently I made a custom fuel rail, and had it and other parts satin nickel plated, which is the process Jaguar used. Similarly a few weeks later I received a twin HD8 set that was poorly installed on the Series II Stromberg manifold. The carbs were rebuilt, the linkage re-designed, and another fuel pipe was fabricated and plated.

If you have a “hybrid” set of carburetors and want them to work as though they were installed at the factory, Island Automotion can help.
