Throttle
and choke
Note the cable routing shown above – this photo was taken looking straight down.
Fit the throttle cable first: undo the front nut completely until it is resting on the inner cable
and then fit the inner cable through the slotted top hole in the bracket and fit the threaded
cable end into the bracket. Fit the lock nut onto the threaded cable end and tighten so that the
lock nuts are in the centre of the threaded cable end.
Fit the barrel end of the cable into the throttle
linkage on the carburettor with a washer each
side and a split pin through the hole in the
barrel end of the cable.
Adjust the throttle cable until at full throttle
(with the panel mounted throttle shafts fully
forward) the throttle linkage is just touching
the front stop on the carburettor. Tighten all
4 lock nuts firmly for the moment – fine
adjustments will be made later.
Put 1 lock nut on the threaded end of the
choke cable and fit it through the bottom hole
in the bracket. Fit the other lock nut,
centering the threaded end in the bracket.
Make sure that the choke drive arm is fully forward and slip the brass ferrule over the inner
cable then fit the ferrule into the hole in the drive arm. Bend the inner cable at right angles in
front of the ferrule. Cut the excess inner cable off. Slip the ferrule through the retaining collar
and fit to the to the drive arm with a washer and split pin fitted to the brass ferrule on the
underside of the drive arm. Refer the photos and drawing on the next page for detail.
Adjust the choke cable until with the choke all the way in the choke arm just touches the stop
on the carburettor body. Tighten the lock nuts firmly.
