Alain de Cadenet is an interesting fellow. Among some he is considered a walking encyclopedia of foreign cars, mostly foreign. He certainly does make mistakes from time to time, especially as it applies to American cars, but all in all, he's a good guy and does some excellent work.
This little blurb about the carb(s) is nothing compared to the time he stuck his foot in his mouth identifying a Chrysler WEDGE engine as the famous "Hemi". Now THAT was almost unforgivable, but it was after all American muscle, not his best area of expertise.
