THE GENERAL DATA

Carburettor Ford elements

1 – a cover of the carburettor,
2 – mobile заслонка диффузора,
3 – a dosing out conic needle,
4 – the holder of a main fuel jet,
5 – a float,
6 – a needle of the valve,
7 – an axis throttle заслонки,
8 – a diaphragm of a regulator mobile заслонки,
9 – elements of the starting arrangement,
10 – the accelerating pump,
11 – the screw of adjustment of a shunting stream,
12 – the screw of adjustment of structure of a mix,
13 – the screw of adjustment of number of turns of idling

Dismantling

PERFORMANCE ORDER
1. To uncover the carburettor, unscrewing seven bolts of its fastening (bolts Torx T20) and to remove a cover lining.
2. To merge fuel from поплавковой chambers.
3. To unscrew four screws of fastening of the holder of the main fuel jet, to extend mobile заслонку диффузора back and to take the holder of the main fuel jet.

The prevention

Not to take out the conic needle co-operating with the main fuel jet. In case of its damage it is necessary to replace all carburettor.


4. To take the unidirectional valve of the accelerating pump.
5. To take a float and the needle valve.
6. To remove a safety casing and to unscrew the screw of adjustment of structure of a mix.
7. To unscrew screws of fastening of a cover of a vacuum regulator, to uncover, a spring, its emphasis and to take a diaphragm.
8. To uncover the accelerating pump, to take a spring and a diaphragm.

Check

PERFORMANCE ORDER
1. To wash up making parts of the carburettor (diaphragms to wash in spirit a solution).
2. To blow compressed air all apertures and jets.
3. To check up a condition of the needle valve, a float, diaphragms, the holder of the main fuel jet, an axis of the throttle valve.
4. To check up a condition of a conic needle and possible ovality of jets.
5. To check up correctness of functioning of the spring establishing position of a needle.

Carburettor assemblage

PERFORMANCE ORDER
1. To insert a diaphragm of the accelerating pump, its spring and a cover (the party with a diaphragm lining in a direction of the case of the carburettor).
2. To insert elements of strengthening of a diaphragm, and also its springing adjusting ring.
3. To insert a diaphragm. The vacuum aperture in the carburettor case should be opposite to an aperture in the case of a vacuum regulator.
4. To insert a spring and a regulator cover.
5. To screw up the screw of adjustment of structure of a mix against the stop and to unscrew it on three turns. This initial position for correct adjustment.
6. To insert a float and its needle valve.
7. To insert a ball of the valve of the accelerating pump and to place its loading in the case channel.
8. To adhere mobile заслонку диффузора in position of the maximum opening and to insert a new lining, and also knot of the main fuel jet.
9. To establish it thus concerning the carburettor case that its flange was at height of a surface of installation of a lining.
10. To establish a new lining of a cover and a cover the carburettor
