I should agree with Bill here and it is something that is so frequently overlooked: on the very-similar carb. fitted to the old two-stroke SAABs (and other old Solexes with which I have dealt) this really can be a problem that upsets the most rigorous tuning attempts, particularly when it comes to balancing multiple carbs.
If it is possible to fit new seals round the spindle (probably did not have one originally, but a suitable one might be found in the SU range if none available for the Solex) and possibly a new spindle (if worn where it makes contact with the body of the carb.), then perfection of balancing will result.
I did not envy a chum who was not getting anywhere fast attempting to balance the eight pots on a relatively modern Lagonda the other day!
