To convert a Automatic choke DFT carburettor into a Manual choke one, you need to go to the scrap yard and find a 1400 Fiesta. You will
need all off the choke and accelerator assembly including small metal linkage bar which
goes from the choke to the butterfly's (Pic 2) You will also need the bracket
for the accelerator and choke cables. I have coloured in red the parts that you
will need in Pic 1. Be sure to keep all nuts and bolts you take of the carburettor.
The first job is to remove the auto choke, to do this undo the three bolts
which hold the casing on and pull off, there should be a plastic disk, take this
off. You should now be left looking at the internals of the choke unit, there
should be three bolts this holding it on, undo the bolts. The auto choke will
still be attached by a small metal linkage bar which goes to the butterflys, which is
attached to the unit by a small bracket, use a 8mm ring spanner to undo the nut
on the end of the shaft. The auto choke should now be free. Remove the small bracket
and the metal linkage bar (Metal bar Pic 2), the bar my be very tricky to remove, make
sure you make a mental note how the bar fitted to the carburettor. Next
you need to remove the accelerator mechanism (Pic 3) to do this bend back
the small piece of metal and undo the 12mm nut, pull the mechanism of, you may
need to "wiggle" it as it is very good fit. This is the most
fidderly job of all, you need the small metal linkage bar from the 1400, Pic 4 shows the
old bar on the left and the 1400 bar on the right, note the difference. Attach
the 1400 bar to the butterfly mechanism as the old one attached. The next job is to modify
the 1400 accelerator bracket. The problem with the 1400 bracket is that it has a
small piece of metal bent out (circled in Pic 5) if this is left on it will stop the carburettor
working properly. Use a hacksaw to cut it off, then file it smooth. Fit the
accelerator bracket, you may want to fit the cable bracket at the same time. (Pic
