Description
Overview:
The Metering Diaphragm for Stihl FR130T, SP90 (part no. 4314 121 4700 / 43141214700) is a genuine Stihl component used inside the carburettor to control fuel flow into the metering chamber. Made from a fuel‐resistant elastomer composite designed to hold shape and flexibility under engine heat and petrol exposure, it helps keep the air-fuel ratio stable across idle and load. Correct metering supports smooth starting, consistent idle, and clean acceleration. Sized to fit specific Stihl carburettors, the diaphragm measures 30 mm x 25 mm (1.18 in x 0.98 in) for an accurate seal and movement. It is intended for a wide range of Stihl handheld petrol machines such as brushcutters and hedge trimmers, including FR130T and SP90.
Key Features:
- Genuine Stihl part for assured fit and performance on listed models
- Regulates fuel metering for stable idle, smooth pick‐up, and reliable running
- Fuel‐resistant, heat‐tolerant construction for durability in everyday use
- Correct 30 mm x 25 mm size (1.18 in x 0.98 in) for the specified carburettors
- Helps prevent lean surging, flooding, and inconsistent throttle response
- Maintains carburettor calibration when replacing a worn or hardened diaphragm
- Straightforward to fit during routine carburettor service or rebuild
- Suitable for blowers, brushcutters, hedge trimmers, Kombi engines, augers, and sprayers in the Stihl range
Typical Applications:
Routine maintenance or repair of Stihl petrol equipment to restore dependable starting and running. Common during carburettor servicing when machines show poor idle, hesitation, or hard starting. Used across landscaping, grounds care, agriculture, and construction tasks on brushcutters, blowers, hedge trimmers, earth augers, pole pruners, Kombi engines, and sprayers.
