Three-Piece Decompression Valve Kit

This kit supplies three new decompression valves compatible with Stihl chainsaw models 026, 029, 036, 066, MS260, MS360, MS381, MS390 and MS660. The valves are designed for single-cylinder, two-stroke petrol engines and allow excess cylinder pressure to escape during starting. Each valve replaces the original equipment part for simplified cold starts.

Sustained Starting Reliability

Under repeated starting cycles the valve maintains consistent pressure relief so the starter cord pulls freely each time. The brass construction resists carbon build-up and heat distortion that can cause sticking after prolonged use. Steady operation reduces operator fatigue during long work sessions in forestry or landscaping.

Threaded Port Compatibility Limit

The valve fits only the specific decompression port thread used on the listed Stihl models. Engines with a different port diameter, thread pitch or seating angle will not accept this part. Buyers who need a valve for other brands or newer Stihl models must verify the port specification before ordering.

Questions about this item

Does the decompression valve change the running noise or heat on my MS260?

The valve only opens during starting to reduce compression; it closes once the engine runs, so normal noise and heat are unchanged.

What must I already have on the saw to fit these valves?

You need a Stihl 026, 029, 036, 066, MS260, MS360, MS381, MS390 or MS660 with the original valve thread intact.

Will these valves work on an older 026 that still has the factory cylinder?

Yes, they are direct replacements for the factory decompression valve on all listed models including the 026.
