Description
Overview:
The Cylinder Gasket for Stihl MS661 and MS661C petrol chainsaws is a thin, precision-cut seal that sits between the cylinder and the crankcase to keep the engine airtight. This Genuine Stihl part is made from a durable, heat- and fuel-resistant composite gasket material designed to cope with two‐stroke operating conditions. A correct seal prevents loss of compression and air leaks that can lead to poor starting, erratic idling, and lean running. Made to Stihl's specification for the MS661 platform, it provides the right fit around transfer, exhaust, and bolt passages for reliable assembly. Supplied under OEM No. 1144 029 2300, it is a direct replacement for worn or damaged gaskets during repairs or top‐end servicing on the MS661 or MS661C.
Key Features:
- Genuine Stihl part for assured compatibility and build quality
- OEM No. 1144 029 2300 for straightforward like‐for‐like replacement
- Precise fit for MS661 and MS661C to maintain correct cylinder height and sealing surfaces
- Helps maintain crankcase compression for strong performance and easier starting
- Reliable seal to reduce air and fuel leaks that can cause lean running and engine damage
- Heat, oil, and fuel resistant composite material for durability in heavy use
- Clean port and bolt hole alignment for simple installation during a top‐end rebuild
- Supports consistent tuning and idle stability after reassembly
- Suitable for professional forestry, arborist, and firewood work as well as DIY maintenance
Typical Applications:
Use when refitting or replacing the cylinder on MS661/MS661C chainsaws, during piston/ring changes, decokes, or rebuilds following seizure or wear. Ideal for resolving air leaks, restoring compression, and ensuring stable carburettor tuning in demanding felling, logging, milling, and general grounds maintenance tasks.
