per BSB67 The valve will dictate where the normal final rocker position is. this made a lot of sense. I had some "smutz" on my adjuster screws, so I cleaned everything up really, really well & re-set the valve lash (problem solved). I don't think I was getting a good "feel" of the pushrods & adjuster screws with the crap on the adjuster threads. Now, the engine sounds like a sewing machine & very even.
