Engine removal - 127 Special and 127
from chassis number 1104290 onwards
94 The removal of the engine assembly from
these models is slightly different from that
described in Chapter 1, owing to redesigned
engine mountings.
95 For the later type of mountings,
disconnection of the engine is achieved by
removal of the engine suspension mounting
securing bolts after taking the weight of the
assembly on a hoist.
96 On refitting the assembly tighten the securing
bolts to the specified torque load.

Carburettors - general
1 On L, C and CL models the 1049 cc engine is
fitted with either a Weber 32 ICEV 161150 or a
Solex C32 TDI/4 carburettor with a downdraught
single venturi and automatic coolant heated
choke (photos).
2 On Sport versions, a dual venturi Weber
carburettor is fitted with manual choke.

Removal and refitting
3 Remove the air cleaner
4 Disconnect the throttle cable (photo).
5 Disconnect the distributor vacuum pipe
(photo). 6 Disconnect the fuel flow and return
hoses 7 Disconnect the coolant hoses from the
automatic choke housing and tie the pipes as
high as possible to prevent coolant loss (photo).
8 Unbolt the carburettor flange mounting bolts
and lift the carburettor from the manifold.
9 Refitting is a reversal of removal, but use a
new flange mounting gasket
Dismantling and adjustment
10 Clean the outside of the carburettor, remove
the top cover screws and lift off the cover.
11 Clean out the float bowl.
12 Any jets or bleed screws if removed, should
only be cleaned by blowing air through them.
Never probe with wire or their calibration will be
ruined.
13 Check the float level by holding the
carburettor cover vertically so that the float
hangs down, and then measure between the
casting flange and the nearest point of the float.
Adjust if necessary by bending the float arm tab
until the clearance conforms with the
Specifications according to carburettor.
14 The automatic choke will not normally require
dismantling, but if the cover is removed, make
sure that the centre index marks on the cover
and housing are in alignment before tightening
the choke cover screws.
15 On later carburettors, the mixture screw is
fitted with a tamperproof cap and adjustment to
the slow-running should therefore be limited to
