Description
Overview:
This Genuine Walbro D20-WAT Carburettor Diaphragm & Gasket Kit replaces the wearable sealing parts inside Walbro two-stroke carburettors to restore correct fuel metering and priming. The kit includes a fuel‐resistant elastomer diaphragm and matching fibre/paper gaskets to refresh aged, stiff or leaking components. It is suitable for a wide range of small petrol engines used on chainsaws, brushcutters/strimmers, hedge trimmers and other handheld equipment. Typical applications include popular machines such as the Husqvarna 225R and Echo CS 2600. Replacing diaphragms and gaskets is routine maintenance on engines that are hard to start, won't hold tune, surge, hesitate or idle poorly, especially after long storage or when modern fuels have hardened the original parts. As a genuine Walbro part, fit and function match the original specification.
Key Features:
- Genuine Walbro components for assured compatibility with Walbro carburettors
- Replaces hardened or damaged diaphragms and gaskets to restore smooth running
- Helps cure issues such as poor starting, erratic idle, bogging and inconsistent tune
- Fuel‐resistant materials designed to cope with modern pump fuels
- Suitable for routine servicing to extend carburettor and engine life
- Straightforward to fit with basic hand tools, minimising downtime
- Supports correct metering, priming and throttle response after refresh
- Cost‐effective repair compared with full carburettor replacement
Typical Applications:
Used during carburettor servicing on handheld two‐stroke equipment such as chainsaws, brushcutters/strimmers and similar small machinery. Ideal when a machine has been stored, when fuel has evaporated and left deposits, or when the engine shows symptoms of air leaks or fuel starvation caused by tired diaphragms and gaskets.
