Nevermind, I found it. However, I'm not too sure I have three of these.

No, you probably don't. SU (Skinner Union) is a British carburetor common
on Brit sports cars of years ago, and still found in the restoration and
rally club world. Often found in tandem, banks of three, and occasionally a
double bank of three.

The point of the reference is not the carburetor itself, but the skill and
knowledge. Most of the people currently adept at tuning a bank of three
carburetors (regardless of manufacturer) will be found around the British
sports car environment, if they haven't yet gone mad.

Of course, you could also go to

and order a manual for your engine.
