10" drum auto adjusters?
You know that the adjusting bar has different threads for each side. One side is right hand thread, the other is left hand thread. I can't remember which is which at this time, but that could cause an issue.
Also is the cable properly wrapped around the 1/4 round bracket and not behind it? Is the end properly hooked into the adjuster lever?
Are you sure that you have the proper parts and someone didn't slip in a mickey???
