Description
Overview:
The Metering Diaphragm Assembly for Makita EH760 petrol hedge trimmer is a Genuine Makita part (MPN 168767-7) that restores accurate fuel control in the carburettor's metering circuit. Built from fuel‐resistant elastomer with fabric reinforcement, the flexible membrane works against the metering lever and needle to regulate fuel delivery, helping the engine start easily, idle smoothly, and accelerate cleanly. It is designed for Makita garden and landscaping equipment using compatible carburettors, including the EH760 and EH561 hedge trimmers. Age, ethanol in fuel, or long storage can cause a diaphragm to harden or distort; replacing it is a routine service fix that brings performance back to specification. This assembly matches the original dimensions and hole pattern for a straightforward refit.
Key Features:
- Genuine Makita component for assured fit and reliability (168767-7)
- Precise fuel metering to maintain correct mixture across idle to full load
- Fuel‐resistant materials suitable for modern pump petrol (E5/E10)
- Direct replacement to original specification for consistent operation

- Durable construction for long service life in regular professional or DIY use
- Installs with standard carburettor fixings during routine maintenance
- Supports stable tuning and reduced need for repeated adjustments
Typical Applications:
Used during carburettor service and repair on Makita petrol hedge trimmers, brushcutters, and blowers when symptoms include hard starting, erratic idle, hesitation on throttle, or surging. Suitable as preventative maintenance after long storage or exposure to stale fuel to restore dependable everyday operation.
