Description

Overview:
The Metering Diaphragm for Stihl carburettors is a fuel‐regulating membrane that controls the metering lever and needle to deliver the correct fuel mix to the engine. This Genuine Stihl part is made from fuel‐resistant elastomer designed to withstand petrol and operating heat, helping maintain stable idling and clean acceleration. It fits a wide range of Stihl machines, including chainsaws and brushcutters, and is an exact match for the Stihl MS270 and MS270C. As an original component with MPN 4116 121 4700, it restores correct carburettor function when a diaphragm has hardened, stretched, or torn through age or fuel exposure, supporting reliable starting and consistent cutting performance.

Key Features:
- Genuine Stihl part for assured fit and function (MPN 4116 121 4700)
- Precisely meters fuel for stable idle, smooth pick‐up, and reduced bogging
- Fuel‐resistant construction for durability under regular use
- Direct replacement with OEM hole pattern and profile for straightforward fitting
- Helps resolve hard starting, surging, and poor throttle response caused by a worn diaphragm
- Suitable for routine carburettor servicing and rebuilds to maintain performance
- Supports efficient running to reduce unnecessary tuning adjustments
- Compatible with many Stihl chainsaws, brushcutters, blowers, and cut‐off saws

Typical Applications:
Used during carburettor maintenance to replace a perished or distorted metering diaphragm on Stihl two‐stroke machines. Typical symptoms include erratic idle, lean or rich running, hesitation under load, and flooding. Ideal for keeping professional and domestic tools operating reliably in forestry, landscaping, grounds maintenance, and construction tasks.

Also known as:
Carburettor metering diaphragm, carb diaphragm, fuel diaphragm, metering membrane, chainsaw diaphragm.
