Description
Overview:
This Diaphragm Assy, Metering is a Genuine Honda replacement part for the carburettor metering circuit on Honda mini 4‐stroke engines, including GX25 and GX35. It is a thin, precision‐moulded, fuel‐resistant elastomer membrane that flexes with pressure changes to regulate fuel flow, keeping the air‐fuel mixture stable across idle and load. Correct metering helps smooth starting, steady idle, and clean acceleration, while reducing hunting and stalling. Built to Honda specifications for thickness and profile, it seals and operates correctly in the original carburettor body without modification. Suitable for handheld garden and light construction machines powered by the listed engines, such as Honda brushcutters and hedge trimmers, it restores reliable performance when the original diaphragm has hardened, warped, or torn through age or fuel exposure.
Key Features:
- Genuine Honda part for assured fit, function, and reliability
- Matches OEM calibration to maintain accurate fuel metering and smooth engine operation
- Fuel‐resistant elastomer construction designed for longevity with modern pump fuels
- Helps resolve hard starting, surging, uneven idle, and hesitation caused by a worn diaphragm
- Direct replacement in the original carburettor; straightforward to install with basic hand tools
- Factory‐specified dimensions for proper sealing and consistent throttle response
- Supports engine efficiency, helping protect against lean running or flooding
- Suitable for routine maintenance or repair of high‐hour machines and seasonal equipment
Typical Applications:
Used during carburettor servicing on Honda GX25/GX35‐powered equipment such as brushcutters and hedge trimmers. Ideal when recommissioning machines after storage, addressing fuel delivery faults, or restoring stable running for professional grounds care, landscaping, and domestic garden maintenance.
Also known as:
Metering diaphragm, carburettor metering membrane, carb diaphragm assembly, Honda carb diaphragm, diaphragm for carburettor metering circuit.
