SU Adjustment: Balancing & Mixture

This video describes the basic tune-up of SU Carburetters--balancing the airflow, and adjusting the mixture. John's demo uses HIF carbs, but the principles apply to all SU's (such as the H-1 and HS2 carbs on our Spridgets), the main difference being that our carbs have mixture adjustment by raising or lowering the jet (while the HIF uses a screw adjustment).
