Description
Overview:
This non-genuine replacement carburettor is designed to match the Zama C1Q-S140 pattern used on Stihl HS81 and HS86 hedgetrimmers. Built with a durable die-cast aluminium body and precision brass metering parts, it restores a correct fuel-air mixture for smooth starting, steady idling and clean acceleration under load. It is a practical fix for machines suffering from hard starting, stalling or poor throttle response due to a worn or contaminated carburettor. The unit is compatible with Zama C1Q-S140 and C1Q-S198A applications and is intended to replace OEM reference 4237 120 0606 on the HS81/HS86 series. Suitable for professional landscapers and home users alike, it helps keep hedge maintenance tools reliable during routine and intensive trimming work.
