Ultramatic throttle linkage adjustment

I'm having issues with the direct drive clutch engagement on my recently purchased 55 Clipper. The previous owner did a carb rebuild and the carb seems to work well. However, I suspect (hope) that the direct drive clutch engagement issue (moaning & slipping) is related to linkage adjustment. In service bulletin 340, it shows how to adjust throttle linkage length, but does not indicate where on the shaft to adjust (set) the transmission cross shaft collar, in relation to the threaded throttle shaft. Any recommendations? Midway in the threaded portion of shaft or so far from either end? Mine was set at the far (firewall) end of the threads, which seems an extreme position. Figure in service bulletin 340 shows collar somewhat midway in threaded portion.
