Description
Overview:
This genuine Walbro carburettor diaphragm kit is designed for the WJ1 series carburettors used on many small two‐stroke petrol engines. Built from fuel‐resistant elastomer diaphragms with matching fibre/composite gaskets, it restores the metering and pump functions that control fuel delivery. Replacing hardened or stretched diaphragms helps recover easy starting, stable idle, and clean acceleration under load. Ideal for professional disc cutters and concrete saws such as the Makita DPC6200 and Stihl TS400, the kit is an OEM solution that fits correctly without guesswork. It is a practical maintenance item for tradespeople, plant hire, and DIY users who need reliable performance from equipment that works in dusty, high‐vibration environments.
