The thrust lever is precluded, against turning "by flats provided on throttle shaft (14).
Thrust lever (22) and carrier (1) have holes of equal diameter uniformly spaced around the periphery; the
carrier is provided with eight holes, and the thrust lever, nine holes.
When mounting thrust washer (24) on the throttle shaft, the setting pin enters the aligned holes of carrier
(1) and thrust lever integrating them into one assembly.
Such a construction of the throttle control unit allows repositioning of the carrier to an angle of 5°.
After installation the throttle control unit is secured on the shaft by crown nut (25) locked with a cotter pin
after tightening.
When installing the thrust lever on the idle stop, the lever bears with its pin (5) against the end of a thrust
screw driven into the carburetor body boss and locked with a lock nut.
When the throttle is fully open, pin (5) of the lever bears against the boss on the body.
2.2.5. Metering System
The metering system comprises a nozzle assembly, a metering needle assembly and a venturi. The
nozzle assembly is pressed into the carburetor body at the lever chamber side and includes nozzle (10) (Ref. Fig.
2) and sleeve (13) pressed onto its one end. The other end of the nozzle has a calibrated orifice which receives
the shaped end of the metering needle assembly. The middle portion of the nozzle has holes serving to release
fuel-air mixture. These holes are so arranged as to smoothly increase the area when being open by the shut-off
edge of the metering needle. Provided inside sleeve (13) is a recess communicating six radial holes of the nozzle
with one large hole in the sleeve. The fuel-air mixture passes through these holes and recess into the mixing
chamber when the carburetor is idling. The second hole in the sleeve is provided to allow the use of the sleeve on
other units.
To align the hole in the sleeve with the corresponding hole in the carburetor body, as well as to ensure
required position of the holes in the mixing chamber relative to the air stream, the sleeve is pressed onto the
nozzle and the nozzle assembly is pressed into the body in a strictly definite position.
To achieve this, milled splines offset from the part center are provided on the end faces of the nozzle and
sleeve. Alignment of the nozzle spline with the sleeve spline indicates correct assembly of this unit.
When pressing the nozzle assembly into the carburetor body the splines should be directed along the lever
chamber and be displaced towards the link chamber.
