Fuel system
If the  lter is not too dirty, its surface can
be cleaned with a brush.
Otherwise it must be replaced.
Check the fuel hose for cracks and leaks.
Make sure that the  lter’s connection neck
is inserted as far as possible into the fuel
hose and that the O-ring is su ciently
tight so that the  lter cannot slide o the
tube.
Fuel pump
The fuel pump facilitates cold starts.
The pump cannot be repaired and must
be replaced if it stops working.
Note how the fuel hoses are connected to
simplify assembly.
Fuel pump
The fuel pump has the task of facilitating
the start of the engine when cold. The
pump  lls the carburettor with fuel before
attempting to start the engine. This also
prevents vapour bubbles from blocking the
narrow fuel channels.
If the pump does not work it must be
replaced.
Note how the fuel hoses are connected to
simplify assembly.
