sounds like its set too loose...try to tighten it down on the spring and then with a aspanner wrench tighten it down........get it so that its a few turns from initial contact with the spring.......that way the spring acts as a lock washer and holds it from turning itself loose.......if that doesnt work then something is wrong with it.
