| contd :- -5- The disadvantage of using light governor weights is the fact that they suffer when the oil is cold and the viscosity affects the small inner piston. We should prefer using stronger xxxxxx control springs and the present governor weights. HS {Lord Ernest Hives - Chair} /W.A.Robotham. | ||
