Do you mean the weights are flopping around? or the mechanisim is free to move?
What are you trying to do with different springs?

The mechanism is moves freely and has springs and from what I have read it needs stronger springs so it is not full advance at idle. What those springs are I do not know. Can you help and do you have the springs I need? Thanks Ron
