Vacuum Talk

I have 21in HG at idle (850rpm) on my vacuum gauge. If I pull the PCV all it does is lower the idle. It doesn't kill the engine or anything. I have a performer intake, and 1406 edelbrock carb. I messed with the mixture screws to get the 21in HG on the gauge. Shouldn't it die? Carb is not running rich, if anything it might be on the lean side. I can put my hand over the carb and it will die.

The pcv deal has got me confused. Its not just the pcv it also does this if the port behind the carb on the intake is open also.
