2 #0015 M2 Hex Nut 12E
2 #0103 M2x5 Threaded Ball 12E

Refer to Drawing #12G
A. Select two #0133 ball links and the #0373 Pushrod. This push rod has extended threaded surfaces and may be
too long for some applications. To determine the correct length, measure the exact distance from the Servo #5
(throttle) spline hole to the center point of the carburetor barrel. Subtract 18.0mm from this distance. The
result will be the total length of the #0373 Pushrod. If any material must be cut, remove approximately half
the required amount from each end. Install two ball links and adjust so that holding the prepared pushrod up
to the original measuring points (the servo center screw hole and the carburetor barrel center point) will show
each directly on center and visible through the hole in each ball link.
B. Select a servo control arm or wheel which is equal or greater in length from center to output hole as compared
to the same measurement on the carburetor control arm. With the servo at Aneutral@ (50% throttle curve of
your transmitter and the throttle stick at the center of its travel) position the servo arm so that its output is
visually perpendicular to a line connecting the servo spline to the carburetor arm mounting bolt centerline.
Determine the position of the carburetor barrel at 50% throttle and attach the carburetor arm with the same
criteria. Install one #0015 M3 Hex Nut and #0103 Control ball in each arm using Blue Loctite.
NOTE: Due to variations in carburetor design, make the determination as to if the carburetor control arm ball
should be inside or outside the carburetor arm based on which will provide a straighter push rod orientation
when viewed from above.
C. Snap the prepared pushrod in place connecting the servo to the carburetor.
