Internal combustion engines use a mixture of air and petrol to generate their power.

The performance therefore is influenced by the air flowing into it and the petrol that is metered out by the carburettor.

Unless the air flow in Twin or Multiple carburettors 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 25 mm to 67 mm (1”-2”) diameter.

Additional Information:

  • 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
