Main system
Under increasing engine speed and heavier loading, the
engine is supplied with a greater quantity of fuel/air by
means of the main system.
Initially, this is achieved by means of the primary stage
only. The fuel flows from the float chamber through the
the carburetor throat. When the throttle valve in .the pri-
mary stage approaches the full—throttle posmon, it actu.
ates the throttle valve of the secondary stage by-means
of a lever, thereby bringing the secondary stage into 0p-
eration. Calibrated holes are prowded In the carburet0r
throat at the same level as the throttle valve, and the
fuel/air mixture is sucked through these holes fmm Spe-
cial transition jets in order to achieve smooth transition
main jet and emu|5ion pipe —where it is mixed With a to the main system of the secondary stage,
given proportion of air — and thence to the spray pipe in
