I have not balanced twin carbs, SU or Stromberg, since the 'seventies & only ever on straight 6 engines but the principle is very simple. Either buy a balancing kit, which I've never used, or remove the air-cleaner(s) & use a flexible tube (rubber/plastic etc) long enough for you to place one end close to the carb intake & the other end to your ear. With the engine idling place the tube partially across the intake, not into it & adjust the carbs individually until the 'hiss' sounds the same from both carbs. Check the throttle linkage opens both carbs together.

Any old haynes tc manual will do. There is a pre set point that needs setting first before you start tweeking. All linkages must be a good fit and all internals in good fettle. Lots of info on the tube and goog. Have fun

Try these instructions which I've used to set up mine. Depending on what you want to spend it's worth buying an air-flow meter (the one from Burlen works better than the Gunson one) and also a Gunson exhaust gas meter. My engine was much smoother after doing this and I've just moved them over to a 3.9 engine that I've just rebuilt and I'm in the process of doing them again.
