In my MS460 shop manual they give the starting settings both for limiter caps and without limiter caps.
My 025 (previous version of the MS250, with screw on caps) has a tank vent that's a piece of fuel line with a screw in it. That's from the factory. When I lost the vent I replaced it with a piece of hose with a screw in it, and it did not work as well as the Stihl version. I ended up buying the Stihl vent for $5 from my dealer.
