Description
Overview:
This non-genuine carburettor is a replacement fuel system component for Mountfield walk-behind petrol lawn mowers, including HP42 R and HP46R (2013). It mixes fuel and air to support easy starting, stable idling, and consistent cutting performance under load. The body is typically made from die-cast aluminium with plastic and brass fittings for durability and corrosion resistance in outdoor use. It replaces OEM No. 118550697/0 and is intended for engines that use a float-bowl, side-draft style carburettor found on the listed Mountfield HP, SP and S-series models. Designed as a direct-fit alternative, it aligns with the original mounting pattern and control linkages, helping restore reliable operation when the old carb is worn, blocked, or beyond cleaning. This is a Non Genuine Part.
Key Features:
- Non-genuine replacement for OEM 118550697/0, offering a practical, cost-effective fix
- Accurate fuel metering to improve starting, throttle response and overall engine stability
- Die-cast aluminium construction with corrosion-resistant fittings for long service life
- Direct-fit design matches the original manifold spacing and linkage geometry on listed models
- Helps resolve common symptoms such as hard starting, surging, stalling or poor idle
- Supports cleaner combustion and efficient running when set up correctly
- Straightforward installation with basic hand tools; no major modifications required
- Suitable for routine refurbishment during seasonal servicing or after fuel contamination
- Consistent performance with modern E5/E10 petrol when maintained to manufacturer guidance
- Sensible choice when the existing carburettor is damaged or uneconomical to repair
Typical Applications:
Used to restore dependable fuel delivery on Mountfield walk-behind mowers for domestic gardens and light commercial grounds care. Ideal after long storage, stale fuel issues, or when cleaning no longer recovers performance. Helps maintain smooth mowing, even grass finish, and reduced engine hunting during regular lawn maintenance.
