I trust you've ensured the diaphragm is still in tact?
Honestly, the only reason that I can think of to keep a ZS on a MGB is to keep the car "original". For a weekend cruiser/random day drive, I would change that carb out for one of those Moss fuel injection kits. But that's only for cars the need to maintain Cali Smog.
If you don't have to keep Cali "smog legal" then I would swap up for a single HS6 or a pair of HS4s.

Check the INSIDE of the original type air filter to see if its dirty.
If you do not have the 2 piece mixture adjusting tool then remove the damper and adjust the misture leaner. Once you know that the mixture allen screw is not stuck and moves easy then you can do it still installed on the car without stressing the rubber diaphram. Bob

And, I was informed by a friend of mine,
to change the oil just before I go as the
probe they put up the pipe can detect the filth
and richness in the oil.
Well, we shall see if all this works out.
Personally, I like the 2 SU's, or the one weber.
I buy cars like hers just for the parts.
Thanks to all for your help.

Ok, leaned the carb out as much as I could,
changed the oil, clean air filter,
made sure everything was on it for the 1978 emissions.
and
it
failed the smog test misserably,
the machine said it is so rich, that it needs
to be pulled off the road and sold to the state
scrap program. 10 degrees BTDC, 850 rpm, passed the visual.
But cannot defy the machine

I recommend register non-op to keep the car...
get the stuff sorted then give them (the smog shop) a visit
a wideband O2 sensor and a AFR gauge before the cat will help w/ the tuning, so you don't have to make a thousand trips to the smog shop while getting it set up.
Are you certain the cat is still good in that car? My '76 ate catalytic converters like they were Pringles... I basically had to get a new one every time I needed to smog :\ Then again, I was also using universal cats from exhaust shops too...
