so here i am trying to install a clutch kit, take off the case cover, remove the screws, and voila a 27mm boss nut that will not come off, tried air, leverage nothing, to make matters worse i snapped the basket in two, all jokes aside how do i get this bitch off so i can replace the broken stuff and get going....? oh while i'm at it how tight do the spring screws need to be when putting them back on? all thanks in advance
