That is weird, but stihl does some crazy stuff.  I have one 020 av with a WT-15 carb in it (walbro) and the other 020 av I have has a HU-7A tillotson in it.  The first, I just rebuilt carb ,fuel lines and manifold boot.  I have about 120 on the compression.  started and ran great  I'm so happy.  Thanks to the people here and the other site i visit.  Don't know about fourth screw on carb need to see it.

what i found out was that your WA-86d is the same as a WT-15 just a H n L and Idle adjust to stop the chain  from turnin

one of my saws has three holes on top, 2 for the pins one is blank,  my other one has 2 holes on top pins in both.  because of the different carbs
