Check of the fuel system

The most common reason for engine failure is a shortcoming in the fuel
system. Many problems can be prevented by regular checks.
Contamination and water by condensation can lead to erratic engine run
or misfiring.
— Check float chamber for dirt and water.
— With bad contamination or formation of water, drain the complete
system inclusive tank, filter and fuel lines, clean and rinse it well.

13.1.3.1) General notes on fuels

Use clean fuel of a registered brand only. Do not store fuel for
longer periods. For storage use only clean, non-translucent,
safety approved fuel containers. If possible avoid the use of
plastic containers. When refuelling from containers, use a fine
mesh screen.
WARNING: Handling of fuel in well ventilated places only.
Never mix fuel in closed rooms. Gasoline is
highly inflammable and under certain
conditions explosive. Do not smoke, no naked
flame or sparks. Do not fill tank brimful, allow
for expansion of fuel. Never refuel while engine
is running.
