Default EC250 doing four stroking

Dear Sirs, I have trouble with the ignition on my EC250 2012.
It seams like it's "four stroking" and will not rev. Have cleaned carburator and changed coil, but still the same problem. See videoclip for reference:

Any suggestion ?

Regards

Vavido

You sure the circlip is still on carb needle?

Dumb question, if you put in gear does it move forward?

I watched the Youtube video, sounds very strange.

Have you tried a new spark plug?

When you remove the spark plug how does it look?

Does the compression feel good when you press the kickstarter?

Remove the reed valve and inspect, is it OK?

Good luck, Dave.

I agree and think the clip came off the needle.
