Description
Overview:
This is a genuine Stihl cylinder and piston assembly for selected 2‐stroke engines used in long‐reach hedge trimmers and multi‐tools. With a Ø 35 mm (1.38 in) bore, it replaces the top end to restore compression, starting and cutting performance on models such as the HL91K and HL94. Built to Stihl OEM standards using durable metal components, it is designed to handle heat, vibration and daily use in garden and professional settings. The kit is supplied with self‐tapping bolts for a secure install and is a direct match to OEM No. 4149 020 1204, making replacement straightforward without modifications. It is suitable for repairing a worn, scored or seized barrel and piston to keep your tool running reliably.
