To the use some materials of the book "CARBURETORS.T2. Of models from 1970 through 1992"is obtained the permission the management http://.shshsh.autodata.ru - "release and wholesale sale to the special literature on the maintenance and the repair of automobiles ".
ADJUSTMENT, the carburetor it is established on the engine.
1. SEALING.



2. CONTROL OF THE FREQUENCY OF THE ROTATION IDLING.
2. 1. Preparatory conditions.
Before beginning of checking or frequency control the rotations of idling and must be preparatory conditions are satisfied. It is necessary to also observe the following special the preparatory conditions: Temperature the cooling fluid of the engine of 80-90°S.
Headlights and accessory equipment must be it is switched off. On the models for (S) and (N) remove the safety device of daylight lamps (A, fig 1).
Lever of the selector of the automatic transmission place in the position "P".
2. 2. Frequency of the rotation of idling and concentration SO.
Technical specifications (TU):

30/32 DID 800±y00 r/min

32/35010 800±y00 r/min
1,0±0,5%SO
1.8L is not more than 0,5% SO.



Primechaniye: Since carburetor has the locked feedback loop, the adjustment of the quality of fuel mixture usually not it is required. On the models for Sweden (SN) reverse connection can be verified, as it is described below in the division 2. 3. If necessary for the adjustment of the quality fuel mixture during the sorting of the carburetors on the automobiles, supplied other countries, you will be turned to point 2.4. division "the adjustment ".
a) give to engine to work approximately half a minute at the frequency of rotation 3000 r/min, then transfer it to the normal idling.
b) press the pedal of gas one time in order to be convinced of that that the regime of the high frequency of the rotation idling it is switched off.
c) Prover'te the frequency of the rotation of idling. If it does not correspond THAT - adjust spirally idling (A, fig 2).

Note: Take into consideration the preparatory conditions, indicated in the division the "idle speed adjustment".
d) press one time the pedal of gas in order to throw out the regime of the high frequency of the rotation of the unmarried motion.
4), after muffling its end.
f) you will neglect engine and give to it to work on idling not less than 5 minutes. Stabilize the frequency of the rotation of idling.
g) you will connect the positive conductor of the voltmeter analog type to the negative conclusion the magnetic valve of feedback (Fig. 5) You will connect the negative conductor of voltmeter k to mass.
Note: The magnetic valve feedback it must be connected.
h) fix the indication of voltmeter on the the unmarried to motion. You will connect the joint of the sensor of oxygen.
i) give to engine to work approximately 10 seconds to 2-etys. r/min.
j) Prover'te the indication of the voltmeter: if the center beat of pointer it corresponds earlier to the recorded value (±0,shch %) - you pass k the following operation. If the center of the displacement pointers does not coincide with that previously recorded by value, by the rotation of the screw of the adjustment of the quality fuel mixture (in, fig. 2) attain the agreement the center of oscillation of pointer with the value indicated with the frequency of the rotation of idling. Afterward adjustment you will repeat points i) and k).
Note: If necessary the regulated frequency of the rotation of the idling spirally (A, fig. 2)
l) with the engine operating at the idling, open throttle plate, in order to the revolutions they increased to 3000 r/min. Shut the choke shutter. You will be convinced of the fact that during increase in the frequency of the rotation of engine the pointer voltmeter it differs from its position on idling it returns to the the initial position during the restoration of the revolutions of the unmarried motion.
m) you will connect hose to the second air to valve.
n) you will establish new stopping.
3. MECHANISM OF PRIOTKRYVANIYA THROTTLE PLATE.
Checking - 12 vol'tnye models THE ACE or PAS

I consider it possible to add following.
Health is one - diseases (or their reasons appearance) thousand... Therefore, besides that described it is necessary to verify:
- the fuel level in the float chamber;
- the condition of the accelerating pump;
- the state the spark plugs, candle wires and tips, the cover of trembler, "sulky", ignition advance and the vacuum corrector of ignition advance;
- the bimetallic spring of "auto-sucking" and the chain of the supply to it of stress, drives shutting and the opening of air damper, the stepped support of the opening of the choke shutter;
- the drive of the opening of second camera;
- the feed pressure of the fuel of nasosa(0,2...0,25 kg/cm.kV.);
- proper working order (T.e. the absence of the loss airtightness, t.n. the "sucking" of air) the actuating elements of carburetor (vacuum diaphragms) and the vacuum system for the control by the attached equipment of carburetor, trembler;
- the capacity of the emulsion tubes, air and fuel jets;
- the state of pair "needle- saddle" float chamber;
- the absence of the wedging of any the fragment of functional diagram (T.e. thrusts) the drives of actuating elements (in t.h. the drive second camera);
i, t.k. the carburetors of these engines (4G13, 4g-37, G54- b) are equipped with the electronic component of control karbyuratora(.EccU), then it is necessary to verify the state:
- the temperature sensor OZH(.BYA), indication which is used ECU(.A54);
- lambda - zonda(.B"2);
- the pressure sensor of the amplifier of the autopilot upravleniya(.Se2y);
- the potentiometer of the choke of zaslonki(.R'shch); - the "cutoff" 3/m valves of zamedleniya(.Yshch");
- the valve of an increase in the frequency KHKH with the start A/S(.Y8SHCH);
- 3/m valves of an increase in the frequency KHKH(.Y99);
- 3/m administrations of the fuel-air of smes'yu(.Yy2ya);
and control circuit of the described executive by the devices of carburetor.
Naturally, to indicate that enumerated as malfunction on your auto- it would be incorrectly, but as THE POSSIBLE reasons their existence it is not excluded. External repair, alas, the matter is hopeless... Therefore I will allow the council itself: before than to return the executor of the correction auto- into the hands of malfunction, you will estimate its professionalism. As and in medicine - the main thing not to do harm. Detailed the description of the "behavior" of auto- and its analysis with institution, warming up, with the different speed the pedal displacement of gas (T.e. the opening throttle plate), with the sharp acceleration on 2-1 and the 3rd transfers, timely conducting TO, the estimation of the state of fuel and air filters, the "stages" of the development of the situation (gradually or "only yesterday in the evening everything was in order, and today...") and t.d., it allows to reduce field of search...
Part of the attached equipment it is described in separate material
