Stihl MS 250

2-Stroke · Also known as: 025

The Stihl MS 250 is a 45.4cc 2-stroke chainsaw and the top model in Stihl's homeowner trio alongside the MS 210 and MS 230. It handles 16" to 18" guide bars and excels at regular firewood production and clearing of medium-diameter trees. The MS 250 shares its Zama C1Q-S112 carburetor with the MS 210 and MS 230 — one rebuild kit covers all three. A documented quirk: primer bulbs on units below serial number 287332321 use OEM 4238 350 6201; later units use OEM 0000 350 6202. The MS 250 superseded the Stihl 025.
