4.2.2. Idling adjustment

Screws of adjustment of system of idling of the carburettor

1 – the screw of quantity of a mix;

2 – the screw of structure (quality) of a mix

Elements of adjustment of idling of the engine include the screw 2 defining structure of a mix, and the screw 1 regulating quantity of a mix. That the owner did not break factory adjustment, on screws 1 and 2 напрессованы the restrictive plastic plugs, allowing to turn screws only on a half-turn. If with plugs it is not possible to adjust the maintenance WITH in the fulfilled gases unscrewing screws, break heads of plugs, turn out screws, remove from them plugs and again wrap screws in the carburettor.

The prevention

At factory establish plugs of dark blue colour, and at servicing deports – red.

Idling adjustment spend on the heated-up engine (temperature of a cooling liquid 90–95 ° With and oils 75–90 °) with the adjusted backlashes in the mechanism газораспределения and with correctly established corner of an advancing of ignition.

1. The screw 1 establish on a tachometre of the stand frequency of rotation of a cranked shaft of 820-900 mines-1.
2. The screw 2 achieve concentration (led 20 ° With and 1013 ГПа (760 mm hg)) WITH in the fulfilled gases within 0,5–1,2 % at the given position of the screw 1.
3. The screw 1 restore frequency of rotation of a cranked shaft to 820–900 mines-1.
4. If necessary the screw 2 restore concentration WITH to 0,5–1,2 %.
5. Напрессуйте on screws restrictive plastic plugs, focusing шлицы plugs concerning adjusting ledges as it is specified in drawing.
