I found the problem, in the description witch came with the engine the red wire should be "ignition" black wire should be "lighting" but it turns out its the other way around.

Well I think its like that as with the black wire connected to the coil I have a beautiful spark.

The engine runs within a meter.

Here you see black wire connected at the coil.

Even the exhaust start to change color after a few minutes off running.

Here a small movie, didn't film much as its a Sunday so I cut in it to make it worthy watching.
