Description
Overview:
This carburettor is a non-genuine replacement part for Mountfield petrol lawn mowers that use the RS100 engine. It replaces OEM No. 1185506970 and is commonly fitted to walk‐behind models such as the HP414 and HP46R. Built with a durable, corrosion‐resistant die‐cast alloy body and hard‐wearing polymer components, it manages the air-fuel mixture to help the engine start easily, idle smoothly and deliver consistent cutting performance. It is suitable for routine maintenance or to restore performance when a worn or blocked carburettor is causing hard starting, stalling or poor throttle response. This Non Genuine Part provides a practical, cost‐effective alternative for Mountfield and selected Stiga machines that share the RS100 engine platform.
