This carb cap features a directional flow, meaning the two holes embedded in this cap will guide the oil in a fixed airflow through the bucket. You can do this by manually turning the top knob in a circular motion when placed on a quartz banger. This process improves the concentration of vapors as the smoke is drawn.
