17. Install a M3 x 5 machine screw in the screw-lock
connector. With the throttle stick centered, position the
carburetor barrel so that it is half-open. Tighten the screw
in the screw-lock connector. Adjust the throttle throw as
needed. We adjusted the throttle endpoints so that the engine
idles reliably with the throttle stick all the way down and can
be stopped using the throttle cut switch on the transmitter.

outer pushrod tube to the support.
