Its a weird one cant work it out, my clutch pedal is a bit stiff and biting point is near top, the problem is the adjuster, if i put the clutch down and rev the engine hard i get a shaky feeling on pedal and a click? And the biting point is higher, so then i reset it and back to normal, how come the ratchet mechanism slips a tooth or so just by revving an engine with the clucth down to the floor??? It even happens in neutral! Weird!! It dosent happen if i drop clucth or anything else..
