You need to do ONE STEP at a time. Don't fricken worry about where your total falls right now, I DOESN'T MATTER. Get the idle sorted out first.
The more you dick around with other areas, the more it will be confusing.
If the idle advance jumps a bunch when you hook up the vacuum advance line, it's not right. There should be ZERO advance from the vacuum can at idle on a ported line.
Just because you blocked off that one point DOES NOT mean you don't have a leak elsewhere. What intake is on the car?
Maybe you really should find someone local that can help you out and walk step by step through the process.
