If you notice any vibration or shaking, continue to make adjustments until the engine runs smoothly both at idle and while revving, through the full rpm range
6. Continue to locate the idle mixture screw and once the air fuel mixture screws have been properly adjusted, and the engine runs smoothly both at idle, and when revved, it is time to locate the idle mixture screw.
7. Finally adjust idle mixture screw until you achieve a smooth idle and also deal with the idle mixture screw has been identified, adjust it until the engine is idling smoothly, with no misfires or shakes, and at the proper speed.
