Description
Overview:
This Gasket & Diaphragm Kit is a Genuine Stihl part for Zama C1Q carburettors used on popular handheld machines such as the Stihl BG55 blower and FS38 trimmer. It replaces worn diaphragms and gaskets that cause hard starting, poor idling, or hesitation under load. The set uses fuel‐resistant elastomer diaphragms and precision‐cut fibre gaskets for a reliable seal with modern petrol blends. Designed as a direct fit for Zama C1Q bodies, it helps restore correct fuel metering and pump action without modifying the carburettor. Suitable for routine servicing or full overhauls on compatible 2‐stroke engines, it supports dependable performance for domestic and trade users alike. Manufacturer Part Number (MPN): 42280071051.
