How Carbalancer solves the problem with precision-speed-simplicity

Why do twin or multiple carburettors need to have a balanced airflow

In order to equalize the airflow through the carburettors, the throttle butterfly assemblies must " be correctly adjusted. To do this, the airflow through each carburettor must first be measured.
Carbalancer measures and indicates the airflow very simply and accurately so that each carburettor throttle butterfly can be synchronized to give the same balanced airflow.
Carbalancer with its unique micro metering-head and easily read scale is the only air balancing device that indicates the air flow in this way and sets new standards of speed and simplicity in carrying out the operation of accurate air throttle calibration.
 

 Internal combustion engines use a mixture of air and petrol to generate their power, so it is obvious when you think about
it that the performance of the engine is as much influenced by the air flowing into it, as by the petrol that is metered by the
carburettor.
Unless the air flow in Twin or Multiple carburettors is correctly set, the correct mixture adjustment is unlikely to be achieved.
In many cases the mixture adjustment of one carburettor may be rendered completely ineffective and may then be inaccurately set, resulting in
poor economy and performance and engine instability.
