Vortex rok gp "pops a Lot"


I have a Vortex super rok (same as GP for the most parts)
I play a lot with my carbing at the moment. Full rev is perfectly. But my area arround 2/3 throttle makes my motor “pop a Lot” where should I start ? My needle is in the middle position at the moment. Float hight arround 3mm
I cant figure out, if these “pops or jumps” from the motor is due to lean or to rich on the carbing ?

Any help is appreciated.

Usually a popping indicates it’s very lean. You mentioned your needle position, have you tried raising the needle (lowering the clip)?

No I have not. Maybe I should try.
