Stihl MS 250: 45.4 cc Chainsaw and the Stihl 025 Successor Platform
The Stihl MS 250 directly replaced the Stihl 025 at the same 45.4 cc displacement with updated engine architecture and improved fuel efficiency. The MS 250 C adds the Easy2Start decompression valve and shares most carburetor, fuel filter, and ignition components with the standard MS 250. Carburetor varnish from ethanol-blend fuel during off-season storage is the leading cause of hard starting on this platform. The chainsaw repair help section covers MS 250 carburetor service, chain sharpening, and bar maintenance.
Most Replaced Parts on the Stihl MS 250
Carburetor for the Stihl MS 250
The MS 250 uses a diaphragm carburetor. Ethanol varnish in the diaphragm chamber and needle valve seat causes most starting and running problems after storage. Cleaning restores function in most cases. When the diaphragm has hardened or cracked, carburetor replacement is the most reliable solution.
Air Filter for the MS 250
Replace the air filter at the start of each cutting season or every 25 hours. In dusty or sawdust-heavy conditions weekly inspection is necessary to protect the engine from abrasive particles.
Spark Plug for the Stihl MS 250
Annual spark plug replacement maintains reliable starting and clean combustion. Always use the two-stroke fuel mixture ratio specified in the Stihl MS 250 owner’s manual.
Drive Chain for the MS 250
Replace the drive chain when it no longer holds tension within the adjustment range or when individual links are cracked or bent. Replace the chain and bar together when either has reached the end of its service life.
