The slow running arrangement has fixed jets and air bleeds feeding into two holes in each throttle bore, one on the suction side and the other on the atmospheric side of the throttle. The suction side hole only is adjustable by a taper needle with a similar effect to our eccentric rotation about the throttle edge. One of the disadvantages to this carburetter is the number of small fixed jets incorporated; another is that the float chamber is open to atmospherics and not balanced with the air intake depression. The accelerator pump is operated directly with the throttle lever and delivers petrol through a common metering plug to a small pipe in each choke tube.
