Range rover blues, I think you were right about goosing my dizzy when I pulled the rotor arm off !!!! I've changed the dizzy for a new one from paddock's and it's running much better. :D My problem is this....... the new dizzy has a plastic plug on the side, is this for lubrication ?? and opposite the vacuum hose, under side off the vacuum chamber. The nodule,( dont know what else to call it :? ) has a black rubber t*t on it. Is this just for transport and needs removing or is it there for the working's of the vacuum chamber. The old dizzy had no t*t on it ??????
