Note: A new gasket must be used when
refitting the carburettor. A tachometer and an
exhaust gas analyser will be required to check
the idle speed and mixture on completion.
Removal
1Disconnect the battery negative lead.
2Remove the air cleaner.
3Relieve the pressure in the cooling system
by unscrewing the expansion tank cap. If the
engine is warm, place a thick rag over the cap
and unscrew the cap slowly as a precaution
against scalding. Refit the cap after relieving
the pressure.4Identify the automatic choke coolant hose
locations, as an aid to refitting, then
disconnect the hoses (being prepared for
coolant spillage.) Either plug the hoses or
secure them with their ends facing upwards to
prevent loss of coolant.
5Disconnect the wiring from the anti-dieselling (anti-run-on) valve.
6Disconnect the fuel hose and vacuum pipe
(see illustration). Plug the end of the fuel
hose to minimise petrol spillage.
7Disconnect the throttle cable from the
carburettor throttle lever (see illustration).
8Remove the two securing nuts and
