The elements of the carburettor that alter the composition of the mixture
depending on the opening of the gate (load or gas), depends on the opening of the
same:
• Zone a: from 0 to ⅛ of load (opening of the throttle). its regulation depends
on the idle screws and the regulation of the mixture and of the idle jet (low
or minimum).
• Zone B: from ⅛ to ¼ load. influenced mainly by the height of the slide bezel.
• Zone c: from ¼ to ¾ load. The carburettor needle is responsible.
• Zone d: from ¾ to full load. The main jet is responsible for this.
iDle jet anD MixinG SCrew
This controls the mixture from the closed position to ⅛ load, but has little effect on
the total opening. To adjust the mixture, the air screw can be turned to change the
air flow, or change the idle jet so that more or less petrol goes in. first turn the air
screw. screwing it inwards enriches the mixture. The air screw must be turned from
a fully closed position. change with half turn increments. if turning the screw from 1
to 2.5 turns does not yield the desired result, change one step in the minimum idle
jet (1) and tune with the air screw (2).
