them cosa clutches can be a serious pain in the tits. I spent about 2 days of non stop work with 5 rebuild kits trying to get the thing to work without dragging. ended up just using an old mk1 clutch and it worked first time
took apart and put back together my cosa clutch AGAIN hoping Id find something wrong w/ my assembly, plates or anything so I'd know the reason it won't work as a relacement of my 7 spring. Arhg! at least the wife let me bring it inside to work where it's warm.
