Description
Overview:
This metering diaphragm is a genuine Stihl OEM part that controls fuel delivery in the carburettor of petrol chainsaws. Made from a fuel-resistant elastomer membrane engineered to stay flexible under heat and vibration, it keeps the metering circuit responsive so the engine maintains the correct air-fuel ratio. The result is reliable starting, steady idling and clean acceleration under load. Designed for older Stihl saws, it is a precise fit for models such as the 032 and 024. As a direct replacement for Stihl part number 1113 121 4700, it restores proper carburettor function without modification and is suitable for routine servicing or repair when the original diaphragm has hardened, warped or torn through age or fuel exposure.
Key Features:
- Genuine Stihl OEM part for assured compatibility and correct fit
- Maintains accurate fuel metering for stable idle and smooth throttle response
- Fuel-resistant elastomer construction for durability in petrol/oil environments
- Helps resolve hard starting, surging, flooding and power loss caused by a fatigued diaphragm

- Suitable for preventative maintenance on frequently used professional and domestic saws
Typical Applications:
Used during carburettor services and rebuilds on Stihl chainsaws to restore proper fuel regulation. Common when addressing issues such as erratic idle, hesitation on acceleration or poor cutting performance. Suitable for forestry, arborist work, landscaping, grounds maintenance and firewood processing where dependable engine behaviour is required.
