Mine is the same way works primary then have to shut off to get back to the starting position.
It worked when I put it back togeather and worked for a while in the truck now I guess I will have to take it off and start all over again.
It did work before I put the spring with the clips on each end on. I will have to get a mirrow and a light and see if it is binding somewhere.
I did get it inspected and have insurance and tags and have been driving it for a week now after working on it for 2 years.
