A - top cover;
B - choke lever housing;
C - choke bi-metal housing;
D - secondary idle jet;
E - secondary throttle vacuum unit;
F - stepper motor;
G - idle mixture adjustment screw;
H - accelerator pump diaphragm;
J - power valve diaphragm;
K - low vacuum enrichment diaphragm;

P - needle valve;
Q - fuel inlet filter;
R - secondary emulsion tube.
- with the carburettor removed from the vehicle, clean it thoroughly externally and place it on a clean worksurface;
- referring to the exploded view of the carburettor, remove each component part whilst making a note of its fitted position;
- make alignment marks on linkages etc.;
- reassemble in the reverse order to dismantling, using new gaskets, O-rings etc.; be careful not to kink the diaphragms;
Ford carburettor Weber 2V float level adjustment:
A - rib on float;
B - adjusting tag;
X - level measurement.
- check the float level as follows; hold the top cover vertically so that the needle valve is closed by the float; measure the dimension from the gasket face of the cover (with the gasket fitted) to the top rib on the float; the correct value is given in the specifications; correct if necessary by bending the tag on the float arm;
- for adjustment of the automatic choke, refer to Ford carburettor Weber 2V automatic choke adjustment.
Ford carburettor Weber 2V automatic choke adjustment:
- disconnect the battery negative lead;
- remove the air cleaner;
- disconnect the feed wire from the choke bi-metal housing;
- make alignment marks if necessary, then remove the three screws which secure the bi- metal housing; detach the housing and recover the heat shield;
Ford carburettor Weber 2V choke vacuum pull-down check:
A - pull-down diaphragm rod;
B - rubber band;
C - screwdriver.
- fit a rubber band over the choke valve lever and tension the rubber band to hold the choke valve closed;
- using a small screwdriver, press the vacuum pull-down rod into the pull-down housing as far as it will go;
- hold the rod in this position and use a drill shank or similar item to measure the clearance between the choke valve and the wall of the primary venturi;
- measure the clearance on the down side of the valve; The desired pull-down clearance is given in the specifications;
- if adjustment is necessary, remove the end plug from the pull-down diaphragm cover;
- turn the adjusting screw located under the plug;
Ford carburettor Weber 2V adjusting the vacuum pull-down:
A - twist drill;
B - rubber band;
C - screwdriver.
- refit the plug when adjustment is correct;
- remove the drill and the rubber band;
- refit the heat shield, making sure it is properly located;
- refit the bi-metal housing, engaging the end of the spring with the choke valve lever;
- fit the three screws, position the housing in its original alignment and tighten the screws;
Ford carburettor Weber 2V bi-metal housing alignment marks:
A - rich;
B - index;
C - lean.
- if the bi-metal housing alignment has been lost, refer to the specifications;
- small deviations from the specified setting may be made to correct over or under-choking;
- reconnect the choke feed wire, refit the air cleaner and reconnect the battery;
- check the idle mixture adjustment.
