vacuum gauge to solve idle issue

Ok so idle issue is back with a vengeance lol. Surges huge at idle or under very low throttle.
Sorry bout lousy video quality. Look at the washer fluid sloshing from the surging lol.
Again I checked for vac leak and couldnt detect any.
Blew out idle air circuits, then snugged the screws in, then out 1 1/2 turns.
Initial timing I set about a week ago 16* BTC
New fuel filter about 200 miles ago.
No visible leaks that I can see.
Ive never had the carb apart(other than checking metering rods), Im thinking it might be time to pull the top off and see whats up??
Heres the videos, sorry bout shitty quality
