Disassembly and assembly of the carburetor (Nissan Primera P10)

Disassembling the carburetor is not difficult, but the following points must be taken into account:

1. The main jets of the carburetor are screwed into the body from above, i.e. in order to get to the jets, you need to remove the carburetor cover.

2. The carburetor cover can be removed after disconnecting the connecting rod, the pump drive rod (spring latch and snap ring), return spring, thrust pin and loosening of bolts.

3. Most of the jets are located in the upper part of the carburetor body and can, for example, be cleaned without further disassembling the carburetor.

4. The mixing tubes can be removed after unscrewing both adjustment air jets in the middle of the carburetor holes.

5. To check the accelerator pump, you can remove the pump lever.

6. On the side of the carburetor, unscrew the viewing window frame and remove the glass with the gasket. The gasket must always be replaced, otherwise gasoline will leak out.

7. To separate the throttle body from the carburetor body, disconnect the connecting rod between the vacuum device and the throttle lever and loosen the three throttle body mounting bolts. The throttle bodies should not be removed.

8. Do not disassemble vacuum devices.

9. Remove the float after pressing out its shaft and unscrew the float needle valve.

10. Clean all parts thoroughly and blow with compressed air. Do not use a needle or other sharp object to clean the jets. The gaskets should always be replaced, even if the removed gaskets still have a satisfactory appearance. To check the accelerator pump, fill the float chamber with fuel and operate the pump. Check that a uniform stream of fuel comes out of the spray nozzle. Assemble the carburetor in the reverse order. All adjustments described in the next chapter, which must be made on the removed carburetor, must be made during assembly.
