Attention! If the floats are not positioned correctly, the carburetor will not operate properly. Therefore, be sure to check the float installation using the template (see Fig. "Adjusting the fuel level in the float chamber").
Warning! Do not clean the jets with metal objects. It is allowed to use thin copper wire. The diameter of the wire should be smaller than the diameter of the hole in the jet. Otherwise, the jet calibration will be disrupted.
1. If the filter mesh is torn or cannot be washed, replace the filter. Replace a tightly compressed or damaged sealing ring.
2. Inspect the floats and gasket. If these parts are damaged, be sure to replace them.
3. If traces of the floats touching the chamber wall are visible, bend the float bracket, then check the installation of the floats using the template.
4. Blow out the channels and holes in the carburetor cover with compressed air. Inspect the mating surfaces of the cover: if there is damage, replace it.
5. Inspect the trigger components. Replace a worn or torn diaphragm, and replace the spring if it is broken or cracked.
6. Blow out the idle fuel jet with compressed air. If the jet is not blown out, clean its hole with a thin copper wire. Clean the other jets in the same way.
7. Inspect the sealing ring. If it is torn, cracked or the rubber has lost its elasticity, replace it.
8. Check the electromagnetic valve. To do this, connect the wire from the "+" terminal of the battery to the valve terminal, and the wire from the "-" terminal to the valve body. The valve needle should be pulled into the body. If this does not happen, replace the valve.
9. Inspect the accelerator pump components. Replace a worn or torn diaphragm. Replace the spring if it is broken or damaged.
10. Inspect the mating surfaces of the accelerator pump cover and carburetor body. Replace parts with damaged surfaces.
11. Check the ease of movement of the lever in the accelerator pump cover. The lever should turn freely, without jamming.

12. Inspect the power mode economizer components. Replace a worn or torn diaphragm. Also replace a broken or damaged spring.
13. Inspect the mating surfaces of the economizer cover and carburetor body. Replace parts with damaged surfaces.
14. Wash and clean the holes of the emulsion tubes with acetone or gasoline.
