The fi rst thing to do when
you get your linkage kit is
to lay out all the pieces
and organize them by size,
length, etc.

The next step is to completely
close the throttle blades by
backing out the idle speed
screws of both carburetors
until the throttle arms stop
moving.

If the rod ends did not come threaded onto
the aluminium hex shafts, that is the next
step. There should be an equal amount
of right- and left-hand male threaded rod
ends. Hex shafts should have one end
marked with a groove cut around it, like
the upper ends in the photo. This typically
indicates left-hand threads. Left-hand
threaded nuts might be a diff erent color
too, like the brass nuts shown. Don’t cross-
thread the aluminum shafts by forcing the
wrong rod ends into them! If they don’t
start threading in easily, try the other end
of the aluminum shaft. Turn all rod ends
all the way in, and make sure they are all
close to the same length and are easy to
turn in and out. Light oil or anti-seize on
the threads can help.
