Restore Engine Compression - with 44mm cylinder and matching piston
Cylinder walls and piston rings form the combustion sealing surfaces; replacing cylinder, piston and rings renews seal integrity and ring tension. Fresh sealing surfaces help re-establish correct compression ratios for the MS251 44mm engine.
Reliable combustion and crisper throttle response should return after replacing worn components and reassembling the engine.
Complete Tune-up in One Kit - thanks to included filters, spark plug and seals
Air and fuel filters trap contaminants that affect combustion, while a new spark plug ensures consistent ignition. Included oil seals, circlips and rings maintain pressure and prevent leaks around the new piston assembly.
A single service replaces common wear items, reducing the need for multiple purchases and repeat visits to a workshop.
Simplified Parts Matching - with official interchange part numbers
Interchange codes 1143 020 1207 and 1143-020-1207 correspond to Stihl reference numbers, allowing buyers to confirm compatibility against manufacturer listings. Clear part numbers minimise the chance of ordering incorrect components.
Buyers can verify fitment quickly using the listed codes, lowering the risk of mistakes when ordering replacement parts.
