I have the clutch adjusted so I have about one inch free play in the clutch peddle. I have a diaphram type pressure plate. Do I adjust this type pressure plate different from the three finger type. I think the book said I needed one inch, but that was with the three finger type clutch. If I tighten things up so the peddle doesn't snap back, aren't I in danger of the clutch slipping? It seems to chatter, at times, now, and it's not very old. Thanks to all.
