OK, got the audio fixed on my laptop so heard your latest video fine. Again, you are confusing the issue by twisting that needle valve so violently. Set it to 1.5 turns out from gently seated, it will start and run that way. Sounds like it “wants to start”, but no quite… Try advancing the throttle closer to the fast position, may you will get it running that way…. At this point, it seems like fuel is flowing to the carb, and the carb is supplying fuel/air mix to the engine… The carb isn’t flooding over is it? You might see a little dribble coming out of the carb throat which is “OK”, but fuel should not be running out of the throat constantly. If you fear the carb is flooding, simply try to start it with the fuel valve closed.
