To fix a throttle on a 120cc mini chopper, first, inspect the throttle cable for any frays or damage; replace it if necessary. Check the throttle grip and ensure it moves freely without obstruction. If the throttle is sticking, clean the throttle housing and lubricate the moving parts. Finally, adjust the cable tension to ensure proper throttle response and verify that the carburetor is functioning correctly.

To fix a flooded mini chopper, first turn off the ignition and remove the spark plug to allow excess fuel to evaporate. Crank the engine a few times to clear out any remaining fuel in the cylinder. After that, clean or replace the spark plug, then reinsert it and try starting the engine again, ensuring to use the choke appropriately. If flooding persists, check the carburetor settings and fuel lines for any issues.
