Bring it back to factory settings and start from the LSN, also put your idle up by half a turn clockwise. The idle limits how much the carb closes and it might be too small and might cause a stall when u let go off the throttle (it happens alot). Your idle should always be consistent, it should always make the same rpm noises, if it changes noise after u do a WOT run to idling your LSN is too rich.

Always do WOT runs after each setting change to clear the crank of the old fuel and let the new settings kick in. Heres a quick tuning flow chart:
