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.

Key Features:
- Genuine Stihl part for assured fit and performance (OEM 4149 020 1204)
- Precision Ø 35 mm (1.38 in) cylinder and matched piston for correct clearances
- Restores engine compression, power output and fuel efficiency
- Includes self‐tapping bolts for a firm, lasting mount
- Manufactured to factory tolerances for smooth running and low vibration
- Durable construction to resist wear, heat and scoring in 2‐stroke use
- Direct replacement on compatible engines; no machining required
- Suitable for HL91/HL94 hedge trimmers and FS/KM 94 power units

Typical Applications:
Used during top‐end rebuilds of Stihl hedge trimmers and combi engines when there is low compression, difficult starting, loss of power, visible scoring or seizure. Ideal for preventative maintenance, fleet servicing, and restoring performance after heavy use or poor lubrication incidents, helping extend the working life of compatible machines.

Customer Questions
I have just ordered piston & cylinder kit. For STIHL FS 94 C Does piston skirt go at back or front?
There is usually an arrow on the top of the piston that points to the exhaust. If by the Piston skirt you mean the extended part at the bottom of the piston this goes towards the carburettor side.
