My header control level has started jumping out of detent. Meaning it won't stay locked down for auto header control, it worked a while yesterday, but for the most of the time, I ran with a piece of rubber wedged against the arm. Looking at the parts manual, I won't see what keeps it locked. The control screw is adjusted to specs. Case_IH dealer is no help, the only way he stays in business is by being the only game for a 100 miles. Any help would be appreciated.
