Carburettor (Weber 2V TLD) - removal and refitting

Caution: Refer to the precautions in Section 1 before proceeding.

Note: A new gasket must be used when refitting the carburettor. A tachometer and an exhaust gas analyser will be required to check the idle speed and mixture on completion.

Removal
1 Disconnect the battery negative lead.

2 Remove the air cleaner.

3 Disconnect the wiring from the antidieselling (anti-run-on) valve.

4 Disconnect the wiring from the automatic choke heater.

5 Disconnect the fuel supply and return hoses, noting their locations to aid refitting.

Plug the ends of the hoses to minimise petrol spillage.

6 Disconnect the link arm from the throttle linkage.

7 Disconnect the vacuum pipe.

8 Release the coolant hose from the bracket under the automatic choke housing.

9 Unscrew the four Torx screws, and lift the carburettor from the inlet manifold. Recover the gasket.

Refitting
11 Refitting is a reversal of removal, bearing in mind the following points.

12 Ensure that the mating faces of the inlet manifold and the carburettor are clean, and use a new gasket.

13 Ensure that all hoses, pipes and wiring are correctly routed, and free from restrictions. If any of the hoses were originally secured with crimped-type clips, discard these, and use new worm-drive clips on refitting.

14 Make sure that the coolant hose is correctly positioned in the bracket under the automatic choke housing.

15 On completion, check and if necessary adjust the idle speed and mixture.
