Fuel pump
The fuel pump has the task of facilitating
the start of the engine when cold. The
pump fi 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.
Dismantle the cylinder cover and starter,
and move the fuel tank to the side.
Note how the fuel hoses are connected to
facilitate assembly.
Pull the fuel hoses off the pump and
dismantle it by pressing on the resilient
plastic tongue (A).
Assemble in reverse order.
NOTE!
The return hose to the fuel
tank shall be fi tted on the long
connection to the fuel pump.
