Frank,
I'm pretty sure I remember reading somewhere that the "swinging" needles
were in fact for some emissions purpose...something about keeping the needle
in contact with the inner wall of the jet , rather than centered, made for a
more controllable (i.e. "smoggable") mixture throughout the range of needle
movement. Or something like that. I could be wrong, of course...
