Removal and installation
When removing the carburetor without removing the engine, make sure that no foreign objects get into the intake manifold opening. There is no need to remove the carburetor to open the float chamber.
- Remove the air filter. To do this, remove the air intake hose, disconnect the exhaust gas return hoses, unscrew the filter mounting bolts and unscrew the wing nut. Lift the air filter and immediately cover the intake opening with a rag.
- Disconnect all connectors connected to the carburetor.
- Unscrew the fuel hose from the carburetor.
- Disconnect the exhaust gas return hoses (if any), having previously marked them.
- Disconnect the distributor vacuum hose from the carburetor.
- Disconnect the gas cable and, if an automatic transmission is installed, also disconnect the throttle cable.
- Disconnect the hose from the engine starter vacuum diaphragm and from the throttle damper.
- Disconnect the idle speed control valve connector, loosen the carburetor nuts and lift the carburetor.
- Place a rag over the intake opening or close the engine hood to prevent foreign objects from entering the engine.

5.1.2. Carburetor overhaul
To disassemble the carburetor, you must have a special set of keys (09860-11011). Lay out all the parts in the order of removal on a workbench covered with paper. After removal, wash the parts with clean fuel and, if possible, blow them with compressed air. When assembling, replace all gaskets and sealing rings. It is better to have a carburetor repair kit. Disassembling and assembling the carburetor is relatively simple and after removal, when the carburetor is on the workbench, it becomes clear how to disassemble it. More difficult are the adjustments, which are described below.
