I have had this problem with two cockers and the stock anti-double ball (hex nut with a spring loaded ball bearing).
Roland, is the BB in the anti double ball still springy? or is it stuck solid? Both the ones i had some how got stuck solid, most probably from a piece of grit getting jammed behing the ball, i have not yet found a way to unjam them so it was Fang ADB's all round.... they're nice
Things you might wanna try are oiling the Ball bearing, or even heating the nut to make it expand and let whatever is jamming the ball fall free. Makes the metal go all ugly tho....
.....assuming that is the problem.
