📖 The small story: the art of fine adjustment

In karting, and especially in the minimum class 60 where the engines are shredded to guarantee sports equity, the difference is often on the details of the focus. The carburation is directly influenced by the weather: the temperature of the air, the humidity and the atmospheric pressure modify the density of oxygen into the engine.

One day of high heat, the air is less dense (there is less oxygen): it is necessary to reduce the size of the nozzle to "deplete" the mixture. Conversely, in cold or rainy weather, the air is heavy and rich in oxygen: it is necessary to increase the size of the nozzle to "enrich" and gover the engine in gasoline, thus avoiding the destructive overheating. Having a 30 to 105 sprinkle set in its toolbox is the secret of any good mechanic to transform a medium kart to gain, session after session.

🔧 Michel's trick

"Michel, our motorist expert, recommends you: to change your main nozzle on a PHBG 18 carburetor, no need to disassemble everything: just unscrew the tank cap located in the bottom of the carburetor. Remember to place a small cloth. Below to recover the few drops of stagnant essence. When tightening the nozzle, show delicacy: screw it by hand to the contact, then give a very small key stroke, but never force as a deaf. Brass is a soft metal, and a damaged thread in the tank will ruin your carburetor. "

⚠️ Security Council: Do not play the apprentices wizards with sprinklers too small in dry weather to look for one tenth of a second. A mixture too poor (unsuitable nozzle) causes critical rise in the temperature inside the combustion chamber, which can melt a piston in a few circuit towers. If in doubt, always start a little rich and gradually get off.

Q: How to identify the size of a nozzle if the engraving fades ?

A: The size is punched on the top of the jet head. However, due to manufacturing tolerances, markings can sometimes be superficial. To avoid confusion in your toolbox, we advise you to store each nozzle in labeled compartments or to measure it with a precision pigement if any doubt remains.

Q: Do I change nozzle between free trials and final ?

A: It all depends on the evolution of the weather. If the outdoor temperature increases considerably between morning and afternoon, or if the sun is the rain, an adaptation of the jet size (mounting one or two points or down) can greatly release or stabilize your engine.
