I.C. engine carburettor adjustment appts - uses depression differences to alter liquid level in test tubes

摘要

The carburettor tuning equipment consists of a number of vertical transparent tubes (10) corresponding to the number of carburettors to be adjusted and partly filled with a liquid and connected with each other at their lower ends (13). The upper ends of the tubes are then connected by flexible piping (8) to the carburettor air intakes, the tubes (10) not required being blanked off by caps (16). The pipes each contain a unit consisting of a housing divided into two chambers (5, 7) by a flexible diaphragm (6). The pipes are connected to their respective carburettor air intakes via a centre aperture in a disc which has a number of concentric grooves to permit fitting to different sized intakes, a second disc having a number of slots fits over the first disc to provide a scale by which the air feed to the carburretor is adjustable.
