A float needle is a critical component in the carburetor of the Citroen 2CV, tasked with regulating the fuel supply to the engine. This thin needle is specifically designed to work precisely with the float, which monitors the fuel level within the carburetor. Due to its slender construction, the float needle ensures a precise seal, preventing fuel leaks. It is crucial for the engine's efficient operation and maintaining an optimal fuel-air mixture, resulting in enhanced performance and reduced fuel consumption. This particular needle is perfectly suited for fitting the classic 2CV models.
