I've just put another engine in with a different clutch casing and disc. using the same gearbox I had previously. Now I'm not getting any gears unless I remove the pedal stopper. Tried a new genuine cable and released the quadrant, but still no luck. The only bit I didn't change was the nylon cup, but it was working fine with my old engine with the same gearbox. Also I don't have an extended release arm.
Any ideas??
