Anti Dive Problem

So friends Now I also have to ask some questions and hope for uncomplicated answers Problem: Have changed the days one of my little ones the fork oil. How that can become so black is a rattle to me. But what’s new in it with real amount – Fits! Now I had to realize that I can turn on the right adjusting screw of the Anti Dive where I want to be without a rest point being feelable. So the screw turns in all directions doof. The left adjusting screw can ic h, how it should be, set in three directions. What is now in the bucket and how can I fix that? Greeting Andy
