I know its frustrating, but it is rare that these engines start on the first attempt.
 
"Some suggestions on your first startup Raphael when you get your engine:
Use the factory settings; the carb needle should be around 1 turn open. After it warms up you can close it a bit to around 7/8th turn closed.

Use a pulley and rope starter if you have one. I actually have never been able to start my engine by hand flipping the flywheels.

Preheat the engine cylinder head with a hair dryer and hot water in the hopper."

Also your fuel tank may be too low. Set it at the same level as the bottom of the engine.
That was a good test of your ignition. Did you notice if it fired at around top dead center? And always be sure you ground the spark plug wire or connect it to the spark plug. If it is not connected to something when it fires, it over stresses the ignition circuit and can destroy it. Good luck!

You need to open the needle at least 1 turn. A bit more if you don't preheat the carb and cylinder.
Don't you have a pulley on one of your other Chinese engines? The crankshaft shafts are the same sise so they will fit right on. But you have to move the right side flywheel in. Loosen the four screws on the flywheel clamp about 2-3 turns. Use a small screwdriver (flat blade, - ) to pop the two halves of the clamp apart. Then you should be able to turn and move the flywheel in. That will give you enough room to mount the pulley

My one starts all the time by flipping the flywheels by hand. Had no problems at all and that was straight from the box

Bonjour,
Second test, a little explosion when I launch it then... Nothing despite alot of needle positions tests

Update: My engine order from Aliexpress just shipped so the New Year's party must be drawing to a close and people are starting to get back to work.

Update: My engine is in the airlines hands at this time, possibly a week yet.
    In the mean time I enjoy watching others discover the difference of how this new model is built.
  The video found on YouTube is interesting, this guy's engine was delivered with a non working governor, he has it working now though not as well as would like.
  The other interesting thing is he says the new cylinder liner is no longer stainless but some type of mild steel that will rust if plain water is used for cooling.
  Also his engine starts well but gets tight as it heats up? I suspect his engine could benifit from a bore polish but difficult to say from just watching the video.
  Also I found a different video where a guy had significant cylinder bore scoring from the wrist pin (old model) is this a common issue? I have considered tapping a set screw from the rear of piston (to keep wrist pin centered) if wrist pin scoring is a common issue...but there may be better ways to address this?
  Thought I would share the video as this is one of the best ways to learn about these engines.

Congratulations on getting your nice little engine sorted.
   I can see with how easy it now starts that you have achieved a good state of tune. Also with the engine base firmly clamped down it runs better then allowing the engine to hop around.
   My Enjoymor has cleared customs, so I expect it to be delivered in a few days.
