Take the ball out and leave the spring In. The lock is not required on
a servo setup. The tiny spring will put a little pressure on the arm to
stop it from rattling so leave it in.

Take the short tab off by grinding the brass end a bit with a Dremel tool then twist the existing tab off (gently) with pliers. Then get a nosewheel steering arm like you would see on a trike gear trainer and put that steering arm on the choke arm. Secure it with a set screw. This should make it easier to open and close with a standard servo.

That would be my suggestion


This could be, I didn't really even think about that because I just thought that this was already done. All you need to so it to take a spare servo arm and notch out the back of it so that it sits around the shaft that the arm is attached to, then put a bolt through the new arm and existing arm. This won't allow it to swivel or twist. Not a great picture but maybe you can see what I mean.
