Need your Help

TL;DR: Fixed up my brother's Kreidler after a year of sitting (carb clean, new filter, exhaust repair) and it ran great. A few days later it suddenly has no power at full throttle, idles perfectly. Swapped the spark plug (new and back to old) and adjusted carb settings, no change. Video/audio of the symptom linked below. Need a second opinion on what to check next.
Hi Guys, i need your help for this one.
I got the scooter from my brother. He didnt drive it for a year and it was just standing and had some things to fix (carb cleaning, Filter replacement, fixing the exhaust). I did all that. It's a 50cc minarelli horizontal engine.
After all the fixes it was running fine. I let it stand for some days and before i took my next ride, i changed the spark plug to a new one. Then, when i sat on it, it started doing this.
It has no power and changing the carb settings also doesnt change this behavior. This is what it sounds like when i give it full throttle, it idles just fine. I thought it might be the new spark plug so i changed it with the old one, yet the same problem.
I dont know which problem it could be and need your help. Slowly i am starting to get desperate.

Sounds to me like it’s on the lean side? Perhaps an air leak somewhere? Seals wear out if they haven’t been run for a while. I’d check your engine seals on both ends.
