You are welcome. I think you should compare the two pieces with the ears visually and you will see where it needs filing. If I remember it correctly I did not have to file the ears down but on the side....Once you do that it will turn smoothly I think, unless there is something else going on. On the spring you don't need to file anything, perhaps you are not putting it together correctly. Try turning it upside down...

I would send you pics if I had mine open...but as I said it may not have been of much help. You have already figured out most of it and you will get the rest done.
