This book is for those people who wish to tune SU carburetors themselves, irrespective of how many carburetors there are on the engine or what type of engine it is. This book explains how to set up carburetors and choose, and even modify, needles for any application, and how to test the engine to make sure that the induction system is tuned for optimum performance.
