1. On early models remove the air filter. On later models disconnect an air pipe from the air filter, then disconnect a vacuum hose and a hose of ventilation of a case from the air chamber. Unscrew three screws and remove the air chamber together with an air line.
2. Disconnect a vacuum tube from the block of a vacuum diaphragm.
3. Using a screw-driver edge, disconnect the spherical hinge of draft of a diaphragm from draft of a secondary butterfly valve.
4. On models 1,6 and 1,8 of l unscrew two screws and remove a separator паров fuels from an arm. Move a separator aside, but do not deform fuel hoses.
5. Unscrew three screws and remove the block of a vacuum diaphragm together with an arm from the carburetor case.
