Description
Overview:
This is a Genuine Stihl engine valve for the FS 130 and FS 130 R trimmers, supplied under OEM part number 4180 025 2003. It is a precision poppet-style valve manufactured from durable, wear‐resistant steel to cope with the high temperatures and stresses inside a 4‐MIX cylinder head. The valve restores correct sealing in the combustion chamber, helping maintain compression, smooth running, and dependable starting. It is designed specifically for Stihl brushcutters, combi engines, pole pruners, and earth augers that share the same 4‐MIX power unit, ensuring correct fit and reliable operation. As a like‐for‐like replacement, it is suitable for routine maintenance or a top‐end repair where the original valve has become worn, burnt, or damaged.
