The base of the carburetor is a duralumin housing. It contains a diffuser (a hole with internal contours). Air is blown through this hole. The oxygen (air) flow rate depends on the cross-section (passage opening) of the diffuser.

The diffuser is equipped with fuel channels. Fuel is drawn from them by an air stream.

Outside the carburetor is installed:

  • fuel pump;
  • jet system;
  • system for adjusting the consistency of fuel with air;

The principle of operation of the carburetor

Phased operation of the device:

  1. Air supply to the tube with an air baffle (damper). The partition controls the intensity of the air flow.
  2. The fuel supply system is certainly narrowed by a mixer to speed up the flow.
  3. Gasoline through the float chamber and nozzle tube with narrowing. A camera with a float adjusts the temporary volume of gasoline. In the float chamber, the pressure level is neutral, and in the tube with narrowing is already small. Due to the pressure drop, fuel leaks through the nozzle.
  4. The acceleration of the air flow contributes to the transfer of fuel (gasoline) and its atomization. Ultimately, an air-fuel mixture of the desired proportion or density appears.
  5. The air-fuel mixture seeps into the engine cylinder through the fuel pipe.

The level of air density in the system depends on the area of ​​the open air damper. The wider the flap is open, the greater the fuel consumption and power.

Simply put, adjusting the carburetor on the brushcutter is creating a good fuel consistency due to the correct air supply.
