One-Tenth of a Screw Turn

["Philip Haldeman" <haldeman@accessone.com>]

Normally, we want to adjust carburetter set-screws in quarter-turns,
sometimes in eighth turns (harder to do by eye).  What happens if we want to
adjust two screws equally by, say, one-tenth turn?  (Or just be sure we've
gone exactly an eighth on each?)  How would one go about making a gauge for
such an adjustment, or does a precision tool already exist?
