Description
Overview:
This cylinder gasket is a Genuine Stihl part designed to seal the joint between the cylinder and crankcase on small 2‐stroke engines. Made from a durable, compression‐resistant fibre composite with good heat and fuel resistance, it helps maintain airtight compression, prevents air and fuel leaks, and supports efficient running. It is engineered for the Stihl FS 94 brushcutter and KM 94 RC Kombi engine, matching the original specification for thickness, cut-outs and bolt pattern. Using the correct gasket is important when refitting or servicing the top end, after decarbonising, or when resolving idle and performance issues. Supplied as a single gasket, Manufacturer Part Number 4149 029 2301, it offers a precise fit and reliable sealing in everyday professional and domestic use.
Key Features:
- Genuine Stihl component for correct fit and material specification
- Precision die‐cut openings for ports, studs and alignment to OEM layout
- Compression‐resistant fibre material; oil and petrol resistant for longevity
- Restores and maintains crankcase and cylinder sealing to preserve compression
- Supports easy starting, stable idle and consistent power delivery
- Direct replacement; installs with standard workshop procedures and torque settings
- Ideal for rebuilds, gasket refreshes or leak repairs on FS 94/KM 94 platforms
- Helps prevent costly damage caused by air leaks and lean running
Typical Applications:
Used during cylinder removal/refit, piston or ring replacement, decarbonising, or when diagnosing and fixing air leaks that cause poor starting, erratic idle, loss of power, or fuel/oil seepage. Suitable for routine maintenance or full top‐end overhauls on compatible Stihl brushcutters, hedge trimmers and Kombi engines.
