Needle valves are important components in the carburettor that regulate the flow of fuel through the carburettor and ensure an even supply to the engine.
They are often made of rubber or plastic and can become worn or damaged over time, resulting in fuel leaks or uneven fuel flow.
Regular maintenance and, if necessary, replacement of the carburettor needle valves is important to ensure optimum carburettor and engine function and to avoid potential problems such as loss of power or engine malfunctions.
