Thanks for the reply.
I have a 1600. Maybe I'm still missing something because although I
can adjust the length of the arms, the throttle that they're connected
to can't be adjusted, so if I shortened one (beyond what is necessary
to have no effect on the idle setting), it would pull up slightly on
that carb's throttle, negating the idle adjustment screw on the carb
itself.
What am I not getting???
