Carburazione e Montaggio Carburatore(2T-4T) Videoguida/Tutorial

Hi everyone, in this video I'll show you how a carburetor works and how to carburete it in general. Subscribe and like ;) Enjoy! Useful tips on carburetion Carburetion is optimal when there's a proper ratio between air and fuel (plus oil in the case of 2-stroke engines). If we have too much fuel, we'll have a rich carburetion, which will cause excessive smoke from the vehicle, fouling of the spark plug, stuttering when revving, and a drop in performance (we'll have an engine that's sluggish when revving). On the other hand, if we have too much air, we'll have a more "nervous" engine that tends to accelerate, and detonations will occur in the combustion chamber caused by fuel bubbles (since the amount of air isn't evenly distributed throughout the chamber). Furthermore, the air explodes at a higher temperature than the fuel, causing our engine to overheat, potentially causing seizures. The symptoms of a lean mixture are: a more pungent engine noise compared to a rich mixture, which has a quieter sound; lack of power delivery, meaning the engine won't pull when accelerating, as if we're squeezing the clutch; and finally, as mentioned above, high operating temperatures. It's best to avoid risks and maintain a rich rather than lean mixture. This doesn't mean we should have an engine that smokes like a skunk, but it does mean our engine doesn't exceed a certain temperature.
