Carburetor for 51 cm petrol driven lawn mower, Faworyt LONCIN compatible (MPN 5901477164200)

Replacement carburetor for petrol-driven lawn mowers with a 51 cm cutting width, compatible with LONCIN-style small engines. This carburetor is designed to regulate the fuel-air mixture delivered to two- or four-stroke engines commonly found in residential and light-commercial mowers. It is intended for maintenance and repair tasks to restore reliable starting, stable idling and consistent engine response when the original carburetor is worn, clogged or damaged. Verify model compatibility and mounting dimensions before installation.

Advantages

The carburetor restores proper fuel metering and air intake control to improve cold starts, reduce stalling at idle and help achieve smoother throttle response under load. Constructed for straightforward replacement, it fits typical mounting arrangements and connection types used on LONCIN-compatible mower engines. By replacing a compromised carburetor, users can avoid excessive fuel consumption and minimize smoke or rough running associated with degraded carburetion.

Suitable for

• Repairing petrol-driven lawn mowers with approximately 51 cm cutting width
• Servicing LONCIN-compatible small petrol engines used in walk-behind mowers
• Workshop or DIY replacement during routine maintenance or carburetor failure
• Restoring engine starting, idling stability and throttle response

Key specifications

• Application: petrol lawn mowers with small single-cylinder engines
• Engine compatibility: LONCIN-style carburetor interface for two- or four-stroke small engines (verify fitment)
• Function: fuel-air mixture regulation with idle and main circuit control
• Mounting: replacement unit designed for standard flange and inlet/outlet arrangements used on compatible mower engines
• Serviceability: adjustable idle and mixture screws accessible for tuning

How to use

Confirm engine compatibility and compare mounting points, throttle linkage and fuel line connections before beginning. Drain fuel or disconnect the fuel supply, then remove the air filter housing to access the original carburetor. Detach throttle and choke linkages, fuel line and mounting fasteners, and replace with the new carburetor making sure gaskets and seals are correctly seated. Reconnect linkages and fuel supply, reinstall the air filter, and check for leaks. Start the engine and allow it to warm up, then perform idle and mixture adjustments according to the engine manufacturer’s specification to achieve stable idling and smooth throttle response.

Usage recommendations

Use clean fuel and a serviceable inline fuel filter to reduce contamination. Inspect and replace gaskets, seals and the air filter when installing the carburetor. Make only small adjustments to idle and mixture screws and verify engine behaviour after each change; if significant tuning is required, consult the engine manual or a qualified technician.
