When the engine is idling, the throttle valve of the 1st chamber 6 is closed. The idle system takes fuel from the emulsion well after the main fuel jet 3 and is fed to the idle fuel jet 12. At the outlet of this jet, the fuel is mixed with air passing through the air jet 13. The emulsion comes out under the throttle valve through the hole of the adjusting screw 15 of the quality (composition) of the idle mixture, while the quantity is determined by the amount of opening of the throttle valve 6 of the 1st chamber.
When the throttle valve is opened, the emulsion also enters through the gap of the transition system of the 1st chamber 16, which ensures a smooth transition from idle to load modes of engine operation. The 2nd chamber has only a transition system.
