CARBURETOR
FL-4
MAINTENANCE NOTICE
1.
Before maintaining the carburetor, the engine, the fuel supply, and the ignition system have to
be in a faultless state. The carburetor can only properly adjusted and faults in the carburetor
system can be detected when there are no mechanical defects in the engine or defectas in the
fuel supply or in the ignition system.
2.
The engine must have warmed up and reached its operating temperature if the adjustments
are to be made when the engine is running.
3.
The air cleaner has to be installed in the vehicle and the filter element must be clean.
4.
Observe that control cables are not kinked or heavily bent in order to ensure a proper
carburetor adjustment.
5.
If for maintenance works the engine must run, pay attention to sufficient ventilation in closed
rooms. Use suitable suctioning units to derive engine exhaust gases. Engine exhaust gases
contain carbon monoxide and can lead to the unconsciousness and to death.
6.
Petrol is bad for health and can cause skin cancer. Any unnecessary skin contact has to be
avoided.
7.
Used fuels are hazardous waste. They have to be disposed carefully and in line with the local
regulations.
8.
Avoid flying sparks, open flames or smoking when working with fuel.
9.
If necessary, mark the position of pipings and their supports prior to dismantling. This makes
the later reinstallation easier.
10.
Always use a new seal when installing the float chamber cover to the carburetor body.
11.
The carburetor float chamber is provided with a fuel drain screw. If the vehicle is not moved
for more than one month, the fuel has to be drained completely. Otherwise, there will be
danger of clogging of bores and jets, which in turn can lead to bad start behaviors or to
malfunctions.
12.
Dried fuel can cause clogging of needle jets bores and channels in the float chamber or the
carburetor body. They must be blown through with compressed air. Do not use needles or the
like to clean the bores since this will damage or enlarge them.
