Speedfight 3 s6 pro replica problems

Hi, so i have peugeot speedfight 3 with chinese 70cc(all ports is the same size and stuff as on original 50cc), stage6 pro replica, original tk 15 carb, stage6 sport pro variator and medium stage6 big clutch spring, small cluths spring are red color(idk the brand, but its starts to take off at around 5-6k rpm), oh and i just put in a new spark plug, that it says original in the manual.

So the problems is that when im taking off the bike boobles like crazy to around 7k rpm and then its starts going, this is really annoying when going from a red light. Originaly there was a 56 jet, I have tried 62,65,68,82 with original airbox, and 70, 75, 80, 82 with mallosi e5 open air filter. But no matter what main jet im putting it it still boobles or just boogs down

Please help me guys, I just want to cut this bike to peaces and put it to scrap metal...
