IMPORTANT INFORMATION

Always confirm the correct OEM part number, engine specification, and carburettor configuration before ordering, as carburettors are manufactured to precise fuel delivery and engine calibration requirements. Installing the correct component is essential to maintain reliable starting, smooth running, and optimum engine performance.

Common signs that a carburettor requires replacement include difficult starting, poor acceleration, inconsistent running, fuel leakage, excessive fuel consumption, engine hesitation, or reduced power output. When replacing the carburettor, it is recommended to inspect the air filter, fuel lines, fuel filter, throttle linkage, gaskets, and associated fuel system components for signs of wear, contamination, or damage. Replacing any worn associated components at the same time will help maximise the reliability and service life of the complete engine fuel system.
