I just put my 21motor (dry clutch) back together in the process of installing the clutch I didn't pay attention to the clutch arm orientation. It was 180 degrees in the wrong direction. Was easy to fix just remove the springs from the clutch. Pull the outer part of the clutch off and then move the arm back to where it goes. Just watch out when you turn the arm that the center part on the clutch doesn't fall out. If it does there is 1 ball bearing between the push rod and the center part in the middle of the clutch.
