That sounds similar to what i have hear & remember. I also have the
little jet centering tool that came with my "SU Tool Kit" that I
bought 30 years ago for my first rebuild. That supposedly holds the
jet centered in relation to the piston while you snug up the jets &
then you replace the tool with the needle & follow the process you
described.

That is something I did not remember...
