Carb Tuning

Share this page

According to SU, if you adjust each screw until the air flow through each carb is the same at the specified idle RPM (600 for the BJ8), the carbs will maintain the same balance throughout the operating range of the engine. You can see this with the SU tuning wires when they rise together as the throttle is opened.
