My Ms290 muffler mod
Runs great, I removed the limiter caps, and the retainer, that Stihl claims is a part of the carburetor. I cannot get that piece, but I did get new screwcaps, did not replace any of that. Did not modify the deflector place, but I did replace the screen. Drilled 1 big hole in the dimple, (center), and 4 smaller one's, around the perimeter.
