• Velocità idle: If the engine idles too fast or too slow, locate the idle speed screw (if present) and adjust it gradually until the engine idles smoothly at the recommended RPM.
• Mixture Screws: Some carburetors may have idle mixture screws. Adjust these only if necessary and with caution, as improper adjustment can affect engine performance and emissions. Typically, turn the screw in until it lightly seats, then back it out 1.5 to 2 turns as a starting point. Fine-tune for the smoothest idle.
