Re:
The lever was wobbly at the pivot where it attached to the body, or so I thought. There's no play in the pivot though.
Thought I'd take it apart, de-grease and put back together. Can't work out how the spring and plate between the inner and outer lever go together. Seems to move the inner lever away from the outer, when I put it back on. Not sure, out of the possible positions, where the plate goes to give tension to the spring, and in the opposite direction.
Any clearer?
