Description
Overview:
The Cylinder With Piston Ø 34 mm for Stihl FS38 is a genuine Stihl top-end assembly designed to restore compression and power in small two‐stroke engines. Made with a durable aluminium alloy cylinder and a precision‐machined piston, it delivers reliable sealing and heat dissipation under regular trimming and brushcutting loads. This OEM replacement maintains factory performance, helping your machine start easily, idle steadily, and produce consistent cutting power. It suits popular handheld tools in the Stihl range, including the FS38 and FS45 brushcutters/trimmers, and is built to match the original 34 mm bore for a correct fit. Supplied as a matched cylinder and piston set, it is suitable for routine rebuilds and repairs where the original cylinder has scored, worn, or lost compression.
