In all my years on this earth, the only unfathomable book I came across was- Aristotles Metaphysics with Analysis..
Recently I have been given a book that equals it...Weber Carburettors by John Pissini.
A challenging book and all I can say is just pay someone to make your Webers perform better.
Life is too short to get into this book from 1968,- V8s didnt exist then apparently- unless you are into Anglias, Healeys and Italian cars
