Hey Chip, Thanks for the comment. With the machines I've looked at I generally find 3 issues that prevent the arm resetting to the original position. 1) Dirt and gunk. There parts have some grease on them and over time the grease gets dirty and stiff. 2)Spring tensioning. The return spring may have lost some of it's tension over the years and therefore doesn't pull back hard enough to return it to the start position. 3) Worn parts. With repeated pulls, the washers, shafts, bushings and inner linings become work cause extra friction that hampers the arm movement. While only 1 of the aforementioned issues can create the problem you are describing, it is generally 2 if not all 3 are contributing factors. My suggestion is to pull the reel mech tray and then disassemble the arm to see what is going on. On my first attempt I added a stronger spring which helped some but did not resolve and when I finally pulled it apart, cleaned it, regreased and replaced the worn parts I had to go back to the original spring because the new one was slamming the arm back with to much force. Most people when the play will pull the arm down and just release it allowing it return with no resistance. If it returned to quickly it can be destrucive to the machine and dangerous if you don't have the machine fully secured to the cabinet it is resting on. Hope this helps!

Did you ever get yours to work? Mine does the same thing.
