Hi, I've got a Fastcut 30 which we bought secondhand several years ago. The clutch has been getting more difficult recently - it doesn't slip but does grab and sometimes doesn't release, so I suspect a lubrication or spring problem. Before I take it apart I'd like to know that I can get replacement springs and shims for the interior of the clutch pack. The local distributor seems to have difficulty getting parts and the ODK store only has the cork pads on offer. Is there another source of springs and shims that I can tap into?
