A 150 cc four-wheeler may not idle down due to several factors, including a malfunctioning idle air control valve, a vacuum leak in the intake system, or an improperly set idle speed. Additionally, a dirty or clogged carburetor can disrupt fuel-air mixture, causing the engine to rev unexpectedly. Fuel issues, such as low-quality fuel or contamination, can also contribute to idling problems. Regular maintenance and inspections can help identify and resolve these issues.
