it sounds like that what you were holding up in your previous pic is a form of single pad slipper clutch that i am not familiar with. Was that piece you were holding the one you mention here mounting to your spur gear? If that is the case look closely at the washers...crap, lol..i clicked reply instead of quick post and now can't see your last post. if you said spring, then you simply need to have adjusted the nut tighter. If you have washers between the nut and plate, then look close at them, they should not be flat washers but spring washers. they should have a mild cone shape to them and if they do, they should be set with the cone cupping toward each other. They are more sensitive than an actual spring to the adjuster nut but you'll figure it out.
