My Middlebridge suffered with clutch judder after having a rebuilt gearbox and new clutch installed. The problem was diagnosed as being a flywheel which had 5 hot spots and a bit of gouging on it. I had the Flywheel skimmed to kill two birds with one stone. Firstly it cured my clutch judder issue and secondly I had extra meat removed from the flywheel to assist engine revving.

Many thanks to Pete for yet another tip. ;o)
