How do you adjust a carburetor on a 90cc dinli?

To adjust the carburetor on a 90cc Dinli, start by locating the adjustment screws, typically the idle and mixture screws. First, set the idle screw to achieve a steady idle speed, then adjust the mixture screw for optimal performance, usually by turning it clockwise until it slightly bogs down and then counter-clockwise until it runs smoothly. Fine-tune both screws as needed while the engine is running. Always ensure the air filter is clean for accurate adjustments.
