. It may be necessary to
reposition the throttle arm so
the throttle rotation is in line
with your throttle servo’s
linkage. To do this, simply
remove the Phillips head screw
(which secures the throttle
arm) and remove the throttle
arm. Flip the orientation of the
throttle arm and reinstall the
Phillips screw.
Install a ball
link and lock nut on the throttle
arm (available at your local hobby shop). Next,
install the linkage from the servo to the throttle
arm. Removal of the throttle return spring is
optional. Removing the spring reduces the load
on the throttle servo, but also bypasses a
necessary safety feature. Remove the throttle
return spring at your own risk.

For ease of installation and
operation, it’s best to install
a hand operated choke
pushrod. A simple Z-bend can
be placed on a 2-56 pushrod
and a loop can be added to the end of the rod. The rod remains
connected to the choke and rests under the cowling. (It’s best to
remove the engine from the aircraft to complete the remaining
portions of step 6.)
If you intend on a servo
operated choke, it’s necessary
to remove the peened arm
and install one of the included
arms. The choke pivot pin
must be removed from the
carburetor to remove the
peened choke arm. To remove
the pivot pin, fi rst remove the
choke fl ap by removing the
Phillips head screw.
Make
sure components do not fall
into the carburetor during this procedure. If this occurs DO NOT
ATTEMPT TO OPERATE THE ENGINE. The components must be
removed and properly reinstalled. (A small ball may fall from the
choke pivot pocket, which must be reinstalled during reassembly.
DO NOT ALLOW THE BALL TO FALL INTO THE CARBURETOR.)
