Happy to see you got a good result, as far as the scraping sound is concerned I'm wondering how much cork is left inside your clutch. It was something I had previously mentioned and had a bit of a concern with. Without disassembling the clutch body move your lever over the the disengaged position and see if you can see any cork inside the slight visible opening that has been created with the cone being moved inwards.
This is just a first port of call as more investigative may well be required.
Cheers,
