Better get measured for those shoes!!
The non-adjustable needles work just fine in the adjustable
carbs.
B1AR needles from the Jag are non-adjustable. My ZS carbs are
adjustable.
I just popped the non adjustable carriers off the B1AR needles, and
disassembled my adjustable carriers. I then placed the B1AR needles in
my
carriers, and reassembled my carbs. Voila.
The needle shanks are the same for both types. It is the
carriers
that are different. Going from non-adjustable to adjustable is cake.
Going from adjustable to non-adjustable is difficult. You will
probably ruin the non-adjustable carrier as it is a crimp fit and
made of brass. Very soft and easily mooshed. I didn't even try to save
the non-adjustable carriers.

P.S. To be fair, the adjustable carriers are made of
teensy-weensy parts
that are easily mangled. You need plenty of light, and a CLEAN, SMOOTH
work surface
and small tools to do the swap. Otherwise if you drop a part, you will
never
find it again. Sneeze at the wrong time, and you will destroy something.
YMMV.

Subject: Re: Tuning ZS carbs, +
Vance---The last time I looked into compatible needles for the ZS
carburetor, there were only a few that were biased and adjustable, such
as the stock, B1AF. The ZS carb manual "selection chart" shows an
asterisk for those claiming to be "adjustable". Burlen Fuel Systems
(and Moss Motors) say this is in error. They are non-adjustable, so
machining must be done to get them to fit these carburetors. This is
what prompts many who modify their engines to go with the SU carburetor,
as changing needles then is a simple matter working the set screw that
holds the needle in the air valve..
If you have found that Burlen now has "hundreds" of adjustable eedles to
fit the ZS, let me know, and I will put on my orthopedic shoes!
