If the throttle shafts don't wobble more than about .010 inches in the
carburettor bodies, I'd simply install new seals rather than rebushing
the carburettors and installing new throttle shafts. Most people don't
realize that one of the improvements Zenith made over the SU design is
the addition of actual rubber throttle shaft seals. Being rubber, they
are a wear item. They are usually supplied in carburettor rebuild kits.
Simply prise out the seal cap with a small screwdriver after you have
removed the throttle linkages, butterfly and shaft.
Have a good time,
