HELP!!! Bogging When Opening the Throttle Fast

I have a terrible bog that kills the motor… It happens when opening the throttle fast. It sounds like applying the kill switch. Spark plug definitely rich looking. I have checked and adjusted pilot jets. I have messed with the needle and the air screw. I have checked for air leaks as well. It’s a YZ125 with a Kehinin 36 PWK Carb. I’ll post a video.
