I believe the colortune is for setting or adjusting the fuel to air ratio. With stromberg carbs, you raise or lower the needle, using a long allen head tool, and watch the colour of the spark. From memory - Yellow/rich, white/lean, blue/correct. Check the instructions!

The colortune does not balance the carbs.
