The inlet pipe is very short and it features an exclusive concentric design and a
geometry that optimizes the air flows when the gases pass through.
The overflow of petrol in the atomizer has been designed to ensure correct flow
dynamic at every position of the throttle valve when opens.
The hole where the petrol enters and the larger needle allow the constant draft even in the most extreme conditions.
The float level, completely made of plastic, and the needle seal are carefully controlled in the production department to ensure the same standard of efficiency over time.
These features considerably simplify the setup of the carburetor.
Thanks to the extremely sophisticated calibration, the petrol-air flows, main and low
jets, have been designed to achieve the best performance with lower consumption.
The compact size of the new carburetor is the result of a careful and meticulous
management of the inner space and the maximum efficiency of all the components,
subjected to strict controls.
