Ok. I did check the air bleeds but not as good as u described. I just inspected from the top down.
And the holley is a 4 corner idle. About one year old barley used.

its kinda a all or nothing deal. if they are not clear then need to be cleaned or you'll never get it right. its easy to do! being a 4 corner you need to do both sides.
