New to forum but this year a Spitfire MK3 driver for 25 years Now a friend asked me to look at his Spitfire which has fitted a 1600 Vitesse engine with twin Stromberg 125. He says that from 4000RPM there's no real grunt from the engine.The car stood for some 7 years and I had to clean out the carburettors. I saw the diameter of the carb outlet is smaller then the inlet manifold. Could it be that there is a manfold fitted that can hold Stromberg 150? I was triggered by the photo that was attached by Pete, and this manifold looks the same as on this Spitfire.
