The fact that "one adjuster is all the way rich" is very suspicious. A first
thought is to check all the electrical components of your carbs, since 90% of
all carb problems are electrical. Make sure the timing is okay at idle and
advances noticeably up through at least 3000rpm. Also if you're setting timing
with a vacuum retard in place make sure it is neither stuck nor leaking. Check
that the carb dashpot springs aren't broken or deformed. (Can you get to the
springs easily on a Z-S? I haven't looked at a Z-S in a long time.)
One final note, I've found that the traditional techniques for setting mixture
and carb balance don't work like they are supposed to until you get them
reasonably close and balanced. If one is opening much more than the other,
trying to balance them is a futile exercise.
