4.5.4.3 Starting problems
The engine is equipped with electric fuel injection (primer) instead of a
choke valve. The automatic control of the primer enables engine starting
with little risk of misoperation.
To inspect the correct functions of the primer the DEI-NT displays a
syringe symbol as long as fuel is injected (primer valve open). With a
cold engine fuel will also be injected after releasing the starter button.
The duration of the injection is dependent on the cylinder head
temperature. With CHT above 40°C (104°F) no fuel will be injected
during engine start.
a) If you suspect that the engine is flooded, e.g. CHT just below 40°C
(104°F) and primer working, you should switch off the primer and try to
start the engine with full throttle. If the engine starts, wait until 3000
RPM are reached, then reduce throttle to keep approx. 3000 RPM.
If the engine is flooded excessively you may close in addition the fuel
cock. As soon as the engine starts open the fuel cock again.
b) If with normal CHT (+5°C (41°F) up to +38°C (100°F)) the engine does
not fire this may be a hint that the fuel filter is dirty and so the amount of
fuel injected is reduced.
The filter has to be cleaned or replaced before take off.
