A carburettor incorporating within its housing and at one end of its mixing chamber a governing diaphragm having balancing springs and being connected with the stem of a poppet-type valve serving as the throttle control, a connection for air of sub- or super-atmospheric pressure varying as an indication of engine speed, and a rotatable manually controlled element within the housing and operating on a carriage to vary the pressure in one of the diaphragm springs to alter the balance of the diaphragm and effect change in throttle setting. |
