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.

Italian Made Spring Clamps

On most SU’s the fuel pipes are 1⁄4 inch outside diameter, and that's just too small for the screw type clamps with perforated bands. The hose oozes through the perforations, they need constant tightening, damage the hose, can distort the pipe, and are tough to remove. We now have a supplier of the Italian made spring clamps appropriate to the hose used on SU and Stromberg carbs. They install with a pair of pliers, provide a constant gentle clamping force, slide back easily to allow quick removal of the hose, and look great.

Three of them are included with any carb rebuild pair that uses hose connections and more are available at very little cost.
