- the float should rotate freely on its axis without touching the walls of the chamber;
- the needle valve must slide freely in its seat without distortion or jamming, and the valve leash must not interfere with the movement of the float tongue.
In order not to confuse the jets of the first and second chambers during assembly, pay attention to the marking of the jets and follow the calibration data table when installing them (see table. Carburetor calibration data 2105-1107010).
Main air jets 3 (see Scheme of the main dosing system of the carburetor and econostat) are marked on the upper plane of the jet head (For example, "170"), which indicates the diameter of the orifice of the jet (1.70 mm).
For the main fuel jets 11, the numbers are applied on the side surface ("107") and also indicate the diameter of the jet hole (1.07mm). The emulsion tubes 13 of the first and second chambers of the carburetor of this car are the same. However, on other car models, they may be different. Therefore, on the cylindrical surface, at the bottom of the tubes, numbers are applied (For example, "F15"), which indicate the tube calibration number.
There are also numbers on the small diffusers 18 (For example, "4,5"), indicating the calibration number of the nozzle opening.
At idle fuel jets, the numbers are knocked out on a cylindrical belt (For example, "50" or "60") and indicate the diameter of the hole (0.50 or 0.60 mm).
Installing the second chamber throttle actuator
Attach stem 8 (see fig. Scheme of the drive throttle easlonok carburetor 2105-1107010) to lever 6 on the axis of the throttle valve of the second chamber is necessary in the following order:
- turn the throttle valve of the second chamber to a vertical position;
- press the rod 8 of the pneumatic drive to the stop and, holding the sleeve 11 from turning, unscrewing or wrapping the rod, adjust its length so that the hole in the tip of the rod 8 is against the pin on the lever 6;
- put the rod 8 on the pin of the lever 6 and secure with a lock washer;
- fasten the stem 8 with a lock nut, holding the sleeve 11 from turning with another wrench.
