For
the solex which are in good
condition general but whose engine does not function, a simple cleaning
is often enough to set out again.
Blocked engine?
The
engines of Solex are relatively easy to give on
the way if the piston is not blocked in the cylinder. To check it, it
is necessary to dismount the mask of the magnetic wheel and to make
turn the wheel to the hand or while pushing Solex, engine in catch. The
engine must turn and present hard points which are times of
compression. Ca makes it possible to also check that the
segmentation of the piston is good. If the magnetic wheel turns in the
vacuum, the moulded key of the wheel and the clutch will be to check.
Attention
so that the engine does not start with
your hand on the magnetic wheel!!!
Lighting
In
the case or the engine is not blocked and has a good compression,
the first stage is the cleaning or the change of the
candle. Its replacement must
absolutely be done by a
candle of same characteristics to prevent that the part inside the
cylinder does not return in contact with the piston at the time of its
increase. To reach the candle, it is simply necessary to remove the air
filter. A possible test to check that the components of lighting are
still good is to go up the wire high voltage on the candle and to put
in contact its lower body with the cylinder. While making turn the
engine (to two: one pushes Solex, the other holds the candle
in position with an insulating grip) of the sparks should be visible.
In the contrary case, the magnetic wheel must be dismounted with an
extractor to allow the cleaning of the contact points, even the change
of the condenser (available nine in the Solex dealers).
Gasoline
The second stage is the cleaning of
the gasoline circuit and in particular of the tank, the
pump and the jet. These bodies are often in good condition but the oil
contained in the gasoline settles slowly with the years of nonuse.
The jet is the only screw on the
carburettor behind the cylinder. It is generally written there
Solex. One cleans it in gasoline, then with a blow of compressed air.
The petrol station is on the front of the engine.
There are four screws to dismount. Attention with their reassembly,
they do not support an important tightening. A cleaning with the
gasoline of the pump and membrane are enough.
The cleaning of the tank is extremely important. It
is necessary to dismount it, empty it of its contents, and to clean it
with water under pressure for example and to rinse it with gasoline
before its reassembly. Attention not to damage the small filter which
is at the bottom, accessible by control between tank and pump.
Starting
After having to check the brakes (Ca will not go
very quickly but good...!) and does not fill the tank with
gasoline with oil 2T 3%, it does not have there any more but to push
Solex, engine in low position, while decompressing with the order with
the handlebar on the first meters. The choke is the small strip behind
the air filter. Completely with thorough on the left, the mixture is
richer in gasoline, thorough on the right, the mixture is less rich.
According to the outside temperature and that of the engine, it will be
necessary to play with this strip. A too rich mixture will not make it
possible to go quickly and the engine like will be attached.
If the engine refuses to start or if its
rate/rhythm is not regular, it will be necessary to go further in
disassembling.
A disassembling of the candle directly after the
attempt at starting will indicate if the mixture reached the cylinder
(wet candle).
The test of the spark is to be made if it were not
carried out before.
Weak performances can come from a worn
segmentation. Ill exists apparatuses relatively good markets to measure
the compression ratios.
