Timing help needed

Ran it twice last week at the track. All seemed well, but still fat and unhappy at idle.

Contemplating trying out that smaller bushing and bumping the initial up before playing with the carb again.

Not to get off track but does everyone agree that if you are under 1.5 turns on the idle mix screws to go with .010 bigger bleeds and if you are over 2 to go .010 smaller?
