Internal combustion engines use a mixture of air and fuel to generate their power. The performance therefore is influenced by the air flowing into it and the fuel that is metered out by the carburetor. Unless the air flow in Twin or Multiple carburetors is correctly set, the correct mixture adjustment is unlikely to be achieved. Suitable for use on SU, Solex, Auto-Lite (Formoco) Stromberg, Weber and Zenith and can be adjusted to fit most carburettors including side-draught, down-draught with air intakes (Venturi) from 25mm to 67mm (1 to 2 inches) diameter

  • Easy read scale indicates the air flow and allows adjustment to optimum efficiency
  • Provides smoother and better acceleration
  • Carbalancer can be adjusted to fit most carburettor
  • Easy to follow instructions

Use Carbalancer to sync carbs and follow-up with Colortune to set the fuel mixture

Pressure bleeding requires a tight fitting cap. European cars with ATE reservoirs use screw on caps. Japanese and American cars use twist on caps. A reservoir with a twist on cap can not be pressurized so you have to use the multipurpose cap described on the left. or the old school method with the help of an assistant.
