altering the throttle speed screw.
16 On earlier carburettors, or if new components
have been fitted to carburettors having a
tamperproof screw, then the slow-running and
mixture can be altered, but only if an exhaust
gas analyser is available in the case of later
carburettors, after the tamperproof cap has been
broken off.
17 On earlier units, use a device such as a
mixture adjustment aid or a vacuum gauge fitted
in accordance with the manufacturers'
instructions to obtain the correct slow-running
adjustment.
18 On later units, an exhaust gas analyser,
again used in accordance with the maker's
instructions, will ensure that the CO level is
within the limits specified. Fit a new tamperproof
cap on completion.
Weber dual venturi carburettor

Removal and refitting
19 These operations are similar to the
operations described in paragraphs 3 to 9 of this
Section, but the unit is of manually operated
choke design and will therefore not have coolant
hose attachments. A choke cable is fitted
instead.
Dismantling and adjustment
20 The operations are similar to those described
for the single venturi type carburettor, once the
upper body has been removed (six screws).
21 If jets are extracted, identify them as to which
side of the carburettor (primary or secondary)
they came from.
