Stihl 020AV super *PIC*

Ken Kimura
Just picked up a 1979-1994 020av super without any manual. Runs great but dies slowly at idle. The L and H screws are clearly marked and easy to figure out. My question is the location of the LA screw. There is no adjuster screw in the hole marked LA on the case but just below the LA hole there is a hole marked MIX. In that hole is an adjuster screw. The carburetor is the Walbro WT-15. Is that the air/fuel mixture screw? I'm thinking different carburetors were fitted on this model and the case provided different holes for those options. I'm reluctant to mess with the screws as the saw works but I have to goose the throttle to keep it going. Thanks for any help. Ken
