Part number 15 is the liikely culprit. I'm not sure whether the pivot can be readily adjusted, as I remember there being too much slop in the threads unless the bolt was tight against the bushing. The washer/nylon end bushings can't be filed, of course, and filing the arms may not work if the bushing has mushroomed at the ends, therefore binding on the nylon bushings.
Thanks for the diagram, though it doesn't clarify whether the bridge (part 21) is threaded. If it is then it's a simple adjustment.
If not then it depends on the bushing #15 being longer than the arm it goes through, so the bolt bottoms to the bushing's face rather than the arm. I doubt the OP will find a new bushing, so since he can't make the bushing longer, he can make the arm a hair thinner to re- establish the proper relationship between the two.
