Description
Overview:
The Diaphragm & Gasket Set for Walbro HDA-series carburettors is a genuine Walbro service kit that restores correct sealing and fuel metering. Built from fuel‐resistant elastomers and quality gasket materials, it stands up to petrol, oil, heat, and regular use. The set replaces worn diaphragms and perished gaskets that cause hard starting, erratic idle, and fuel leaks, helping your engine run cleanly and reliably. Designed for a wide range of HDA models, including HDA 15 and HDA 19, it suits many two-stroke tools used in gardening and construction, such as chainsaws, blowers, brushcutters, and cut‐off saws. As a Genuine Part, it matches the original thicknesses and hole patterns for dependable performance and fit. OEM reference: D22‐HDA.
