The top tension on my new D9 is too tIght unless I have the adjustment screw almost off the spindle so I took it apart to clean in case that was the problem. There is a small flat disk inside the spring which doesn't seem to do anything so I wonder if it has been put together wrong. I have attached a picture of the parts laid out the way they came off the machine. Let me know if something looks awry.
