Description
Overview:
This non-genuine Decompression Plug is a direct replacement for Stihl chainsaws and replaces OEM part 1122 025 2200. Fitted to the cylinder, it provides a momentary pressure release to lower cylinder compression during starting, helping the engine turn over more easily. Built with a durable metal body and a fuel‐resistant rubber O‐ring for a positive seal, it is suitable for petrol two‐stroke saws such as the Stihl MS 240 and MS 360. The plug screws into the existing decompression port and restores reliable starting performance on machines where the original valve has worn or begun to leak. A practical service part for routine maintenance, it is supplied under MPN 350 500 and offers a dependable, cost‐effective alternative to a genuine valve for everyday use.
Key Features:
- Non Genuine Part that replaces OEM 1122 025 2200 for a straightforward fit
- Reduces engine compression during starting to lower pull effort on the recoil starter
- Robust metal construction with fuel- and heat‐resistant sealing O‐ring
- Helps protect starter cords and mechanisms by reducing strain at start‐up
- Direct screw‐in replacement using the existing decompression port; no modifications required
- Suitable for regular professional and DIY use on the listed Stihl models
- Stable sealing to maintain engine performance and prevent compression leaks
- Practical service item to restore easy starting on older or hard‐starting saws
- Supplied under MPN 350 500 for easy identification
Typical Applications:
Used when a chainsaw becomes hard to pull over, especially in cold weather, after top‐end work, or when the original valve leaks. Common in forestry, arborist work, landscaping, firewood preparation, and grounds maintenance where reliable, repeatable cold and hot starts are important. Ideal during routine servicing or when refurbishing a saw to improve starting behaviour.
