Fixing a Stihl HS80

[Vissertw]

It looks like that hole has no function, you were right.
He runs now, not too good at first, but I need to say I forgot to unscrew the mixture screw in order to clean both the hole and screw itself.
After having done that and adjusted to the basic, screw in and one whole turn back it runs great now, both revving up and idle.
Should I make some fine adjustment on the mixture screw or can I leave it this way?

thanks for all the advice so far,

Regards,

Ton.

Per the SM that is the basic setting and is okay; unless, you have a tach to fine with to avoid tuning too lean.
