Occasionally this float may be leak. This can be checked
clearly by holding it up to the light, a leaking float shows
the mixture inside.
When assembling the float take care that the float needle
joins the guide in the bottom of the floatchamber as well
as the guide in the cover.
This can be checked easely by shaking the carburettor
after mounting the floatchamber cover (screws not yet
tightened).
The float operates properly if one hears it moving up and
down.
Make sure that the pointed end of the float needle is in
an upward position.
The idling speed of the engine can be adjusted by means
of the adjusting screw nr. 89. Turning the screw
clock-
wise will increase the idling speed, turning the screw
anticlockwise will decrease it (Throttle valve moves up or
down).
Take care that the gascable has the right length, making
sure that the throttle valve can descend to the bottom of
the chamber indeed.
The carburettor also has a choke valve nr. 95. Pulling the
choke will cut-off the air supply nearly, thus providing an
additional rich mixture for the engine.
Also the choke cable must have the right length enabling
a full open intake diameter.
The banjo bolt nr. 103 is supplied with a little fuel strainer
nr. 102.
Due to the fact that the tap in the fuel tank is also
supplied with a strainer, it very seldom happens that the
banjo strainer is stopped up.
Intake silencer
The 20 and 25
mph.
engines have similar silencers. Both
are supplied with an intake tube diameter 14 mm. (.55").
The 30 mph. engines are supplied with a tube diameter
16 mm. (.63").
The filter of the silencer must be cleaned in gas every
500 miles and moistened with oil afterwards.
After fitting the silencer do not forget to apply the rubber
seal on the junction carburettor-silencer.
Never ride a moped without an intake tube or with
shortened intake tube.
By doing so the power of the engine will not increase,
the only result is that dirt will be sucked into the engine,
causing serious engine troubles!
This is also the case after drilling holes into the intake
silencer!!
