CARBURETOR FOMOCO, MODEL 1969—1970
As from model 1969 the car is equipped with a FoMOC0
down-draught carburetor. The fuel feeding is regulated
by fixed jets mounted in the carburetor body. Only the
main jet is removable. In the body there are drilled fuel
ducts, and also air ducts. In the emulsion tube is — at an
early Stage — a certain amount of air being mixed in With
the fuel.
The carburetor has an automatic choke device with fast
idle and accelerating pump. The carburetor differs from
the Solex carburetor previously used, especially by it that
only the main jet is removable and the fast idle device sit-
uated on the outside of the carburetor. The fast idle has
four steps out of which the fourth step is engaged at the
start only. As soon as the accelerator pedal is touched
upon, the said step is disengaged independently of the
cooling water temperature. Then fast idle works with
three steps like the Solex carburetor previously used.
Adjustment of fast idle, accelerating pump capacitY. float
chamber ventilation and float level is made by bending
control rods and levers. These have, at the factory, been
adjusted to prescribed measurements, and a readjustment
at the garage is therefore — as a rule — not required.
