now I'm going to post another photo.? ? I lossened that screw,I tried to rotate the hook but the problem is that the needle goes to clash against a solid circular part, and it is too invisible in the common correct position.
the axis, as before can advance to right a pair of millimeters, but it should walk this two millimeters to left for turning free without clashing , or crashing. I tried to disassemble? the part that begin the brush, . the screw? goes away easy, but the round semisound part seems soldered, perhaps by sludge.? I am confused. what do you think?
