Got Dad’s various power yard tools here. The battery stuff all works fine, and will be going on FBMP in the next couple of days.
This Stihl FS 90 doesn’t start.

I bought it a can of Stihl’s fancy 50:1 gas. Got spark. Got air. I need to check the valve lash. I don’t know when it last ran, though it has been a few years. Gas tank was empty when I picked it up, but I don’t know if it was empty when stored. Carb looks ok, not gummed up.
Going to buy it a new carb. If that works, and it runs, it goes on FBMP too.
