Notes and Safety Carburetor for scooters, motorcycles and mopedsThe smooth operation and optimum power output of your scooter, motorcycle or moped depends, among other things, on the carburetor, whose job is to create the right mixture of air and gasoline.How the carburetor worksWhen the rider operates the throttle, the carburetor slide moves upwards, increasing the air flow that is sucked in through the air filter. The carburetor then mixes this air with petrol, creating a combustible mixture. This mixture is fed into the cylinder through the intake manifold and the reed valve.The carburetor is equipped with jets to adjust the ratio of fuel and air and thus ensure an optimum air-fuel ratio.
