Default Dle-55 choke arm sticking

I have a Dle-55 engine and the choke lever is hard as heck to rotate. I think I may have bent the arm somehow.
Has anyone had a problem with this. It worked fine before I put a ball link on the end of the arm. I don't see any
way that this post that holds the arm on comes off. I put some wd-40 on the arm and post, but it is still stiff as all
get out. I was in the process of attaching a servo to this arm to open and close the choke, but it is too stiff for a servo
to move. I can just barely move it with my hand. Anyone have a solution to this problem? Thanks, Aframe2

If you look at the air intake opening of the carb and look at that face, you can see where the choke shaft is visible through a small hole. Here the choke shaft has a ring groove also visible. On the inside there is a steel ball and spring pushing the ball into the groove. The groove also has a detent hollow machined into it.

To remove the choke shaft remove the screw holding the choke plate.
Remove the choke plate
Then pull gentlly on the shaft just enough at first to pull the shaft over the ball.
Then pull until the camfered end starts to near the ball and spring being carefull not to lolse them
Remove the ball and spring.
Pull the shaft out.

Reverse this to reassemble using loctite on the plate screw.

Tightening the carb mounting bolts too tight can cause this
