11. Make the throttle pushrod by threading a nylon clevis
and silicone clevis retainer onto the remaining 17-3/4" [451mm]
pushrod. The pushrod must be bent so that the clevis will
clear the engine mount screw nearest to the throttle arm on
the carburetor. Before bending the wire, insert the pushrod
into the throttle pushrod tube and mark on the wire where the
bends will need to be made. Make any adjustments to the wire
until the clevis can pass over the screw head without contact
when the clevis is attached to the outer hole in the throttle
arm. The pushrod must also be able to move the complete
travel of the carburetor without binding. Note: the muffl er was
removed to better show detail of the throttle pushrod.

12. When you are satisfi ed that the throttle pushrod will
freely move the throttle arm, loosely thread a 4-40 x 1/4"
[6.4 mm] socket head cap screw into the screw-lock connector
on the throttle servo arm. Insert the throttle pushrod through
the screw-lock connector and reconnect it to the throttle arm.
Rotate the carb half open and tighten the socket head screw
in the screw-lock connector.
