- disconnect the fuel supply and return hoses from the carburettor, noting their locations to aid refitting, and plug their ends to minimise petrol spillage;
- disconnect the wiring from the automatic choke;
- disconnect the wiring from the anti-dieselling (anti-run-on) valve;
- remove the four Torx screws securing the carburettor to the inlet manifold;
- remove the two securing screws, and lift off the carburettor top cover, leaving the carburettor main body in place on the inlet manifold;
- slide the float retaining pin from the carburettor top cover, tapping it gently if necessary, then lift out the float and needle valve;
- if desired, the needle valve housing can be unscrewed from the top cover;
- recover the washer and discard it; a new one must be fitted on reassembly;
- inspect the components for damage, and renew as necessary;
- check the needle valve for wear, and check the float assembly for leaks by shaking it to see if it contains petrol;
Ford carburettor Weber 2V TLD float level adjustment:
A - check dimension;
B - adjustment tag.
- refitting is a reversal of removal, bearing in mind the following points: use a new washer when refitting the needle valve housing; when refitting the float and needle valve, ensure that the tag on the float locates under the spring clip on the needle valve; check that the float and needle valve operate smoothly; check and, if necessary, adjust the float level as described below; ensure that the carburettor mating surfaces are clean then fit a new gasket onto the main body and refit the carburettor top cover; i the fuel hoses were originally secured with crimped clips, discard these and secure the hoses in position with new worm drive hose clips; on completion, check and if necessary adjust the idle speed and mixture;
- with the carburettor top cover removed as described above, proceed as follows;
- fit a new gasket to the top cover, then hold the carburettor top cover in a vertical position, with the needle valve uppermost and shut;
- measure the distance between the top cover gasket and the bottom of the float;
- if the distance is not as specified, adjust by bending the tag on the float assembly;
- refit the carburettor top cover by reversing the removal operations.
