Must be a older unit.  Has screw on stihl cap and not the flippy cap bs.

Just the china made zama carb acting up.  Got it running and idling all day. Even taken throttle after warming up very good. Still little bit of feathering when cold though.

Hedge trimmer attachment was nice to use and check it out with.

It was a very strong engine, the FS 85 was one of their most popular trimmers. Too bad the EPA had to mess with a good thing. >:(
