38 This adjustment can be made with the
carburettor removed using a vacuum pump,
or with the carburettor fitted and the engine
running.
39 Turn the choke lever so that the choke is
fully closed (see illustration).
40 With the engine running or vacuum
applied, check that the gap between the lower
edge of the choke valve and the barrel is 3.25
mm. Use a twist drill to make the check, and if
adjustment is necessary, turn the screw
located in the end of the vacuum capsule.

Float level

42 To check the float level, hold the cover
vertically with the gasket in place. Check that
the dimension is as specified (see

, and if necessary bend the
tongue on the float arm to correct it.

Choke opening after starting

43 To adjust the cold start device choke
opening after starting, Peugeot tool No 0.145G
is essential. The carburettor must be fitted and
the engine must be at normal operating
temperature and idling at the specified idle
speed (the cooling fan should have cut in and
out at least twice). The air cleaner hose and
the cold start device cover must be removed,
and the transmission selector lever should be
in the Park (P) position.

44 Fit the tool, then slacken the locknut and
turn the adjusting screw to bring the end of
the cam just into contact with the peg on the
tool (see illustration).
45 Using a 9.5 mm twist drill, check that the
choke flap has opened by 9.5 mm - if not,
adjust by means of the adjusting screw (see
illustration)
.
46 Disconnect and plug the diaphragm
vacuum hose, and using a 5.5 mm twist drill,

check that the choke flap has opened by 5.5
mm if not, loosen the clamp screw then hold
the roller against the top of the cam, and
adjust the lever until the drill will just pass (see
illustration)
. Tighten the screw and reconnect
the hose on completion.

Positive throttle opening

47 With the choke opening after starting
adjusted as described previously, press the
roller to open the choke flap and check that
the engine speed is 2000 rpm with the cooling
fan stopped. If necessary, adjust the screw to
obtain the specified speed (see illustration).
48 To adjust the choke cam, Peugeot tool No
0.145G must again be used. Fit the tool,
loosen the locknut, and adjust the screw until
the cam contacts peg (see illustration).
Tighten the locknut on completion.
49 With the adjustments completed, stop the
engine and refit the cold start device cover
and the air cleaner hose.
