The throttle plates i n carburetter are on a common spindle and the synchronising
linkage between the corburetters ensures that the throttle plates i n each carburetter
open an identical amount. I t should be remembered that barrel supplies one
cylinder only, since the inlet tracts are not interconnected. Apart from the throttle
linkage, the carburetters are identical, and each carburetter is, i n effect, two
carburetters w i t h duplicated main jets, idling jets, etc.
However, each has an accelerator jet, there i s one diaphragm
type accelerator pump per carburetter, and feeds both jets. To facilitate cold
a progressive starting device is fitted, discharging mixture into both barrels
on the engine side o f the throttle plates. The
jets, main and air correction
jets, together with their emulsion tubes, are accessible after removing the small
rectangular cover secured with screws t o the top of the chamber cover.
A
