Have a 71 RR Silver Shadow Coupe, which runs two SU carbs. They are great carbs - very simple and easy to adjust, very understandable. Synchronizing them is more a matter of the mechanical linkage being tight and properly adjusted, than a matter of individual carb settings. For the settings, I turn each carb adjustment to zero and then set them to the factory recommended set ups. The linkage, however, is another matter. There are a number of calibrations to pay attention to in order to be sure that the movements of the throttles are identical.

Using them on a performance Model A?? I'd recommend it, but pay attention to getting the proper intake manifold and be sure the linkages to each carb are proper. There are several publications on tuning SU's.

For now, I'm keeping the Zenith double venturi on my e28. It works fine.
