SOLVED: look at your Onan 4K genset for me?

I believe the metal coil element is going overcenter as it lengthens.
Here is the inside of the adjuster, from an ebay listing. The orientation of the prongs is not going to affect anything.
Here is a picture of the element.
I rotated it and added a line to mimic the rod going to the choke lever. The coil expands as it warms up. It lengthens, and the end of it moves to the left in the photo, pulling the choke rod. So that end is either continuing to wrap around the circle and then getting stuck as it cools, or the tab sticking up is catching something. Or the little cover no. 11 shown in the parts drawing is catching something.
I'm going to get my MH into my workshop later this week. The choke is stuck open now. I will get something figured out.
