The air screw on a carburetor regulates the air-fuel mixture at idle, and if the carburetor isn't idling properly, it may be due to several factors. These can include an improper air-fuel mixture, a clogged idle jet, or vacuum leaks that disrupt the airflow. Additionally, if the throttle plate is not closing fully, or if the idle speed is incorrectly set, it can prevent the carburetor from achieving a stable idle. Proper tuning and maintenance are essential for optimal performance.
