Eiri KY PIK-20 E - Starting the Engine; Warm-Up and Taxiing

PIK-20 E Flight manual
The electric fuel pump helps the starting and it should be on. The de
compressor must be closed. Turn radio and other electrical equipment
off.
5.7 Starting the engine
When starting the engine 3/4 choke is required. The throttle should be
opened about 1/4. When connecting the main switch and the electric
fuel pump on, the sound from circling fuel can be heard when every 
thing is in order. If the engine does not start within ten seconds, the
starter should be allowed too cool down a little before the next attempt.
When the engine is running the choke must be adjusted. Otherwise
the mixture is too rich.
When starting a hot engine no choke is required. The throttle should
be more than half opened. If the engine has just been running, the elect 
ric fuel pump may be left off.
If the engine does not start, some choke and less throttle may be
used.
If there is a reason to think that the engine is flooding, the choke
should be fully off and throttle fully open. By pulling the decompression
lever and at the same time cranking the engine with the starter, the ext 
ra fuel is effectively removed from the engine. When the decompression
valves are closed, the starting can be continued normally.
5.8 Warm-up and taxiing
Let the engine run for about 2 min. with 2000 rpm. The warm-up can be
made during taxiing. The choke can usually be closed soon after the en 
gine
has started. The throttle may be handled with rather fast move 
ments to get a good engine rpm response.
More than 2000 rpm should be used during the warm-up and normal
operation, in order to have the engine running smoothly.
The engine is warm when the throttle can be opened without the en 
gine faltering. This corresponds to about 100°C cylinder head tempera 
ture.
During taxiing one wingtip wheel is down and the stick fully pulled.
The flaps are recommended to be kept up (negative), in order to have
more ground clearance at the ailerons.
