I am not sure if you know what I mean concerning properly setting up the engagement. Imagine a 3 legged stool with a bucket of water on top. Also, imagine one leg is 1/4 inch longer. Now, gently lift it off the ground and and set it back down perfectly straight - vertically. Obviously the long leg would touch first causing a sudden jolt as it would tilt to the others and this would disturb the water (one chatter cycle). With a clutch your target would be to ensure that the settings would allow all three legs to engage the floor at the same time. Get it? Now, the clutch has these legs and what is important is that they will need to engage at the same time, not cocking the mechanism and causing chatter.
