It also bogs down on sharp turns, it gets worse the slower I go. I checked the vacuum and it is steady in the fact that the needle doesnt bounce quickly, but when the engine stumbles the vacuum does change with the rpm change. I thought it could be the brake booster but all of the tests I did on it seemed to pass. Im beginning to think that it is still a carb issue, like the change in motion while stopping or turning is somehow effecting it?

There's no such thing as stupid people. You did a very smart thing. You asked for help. And besides, cars is hard.
Anyhoo, it could be anything that gets vacuum. Oh and the vacuum drops when the engine stumbles because it's not running as fast. (not sucking in air as hard) Perfectly normal. Did you replace the vacuum hose to the PCV valve too? Sounds like the PCV was bad but the vac hose could be too. Could it be the carb, sure. Bogging when it turns or stops or whatever could be a sign the float is out of adjustment or just plain old sunk. Either of those conditions can allow the carb bowl to over fill when turning, stopping (maybe even going up or down steep hills) which in turn floods the motor. (making it bog down or die) You'll have to take the top off the carb to check that. Not too hard usually. Um, 2 bbl or 4 bbl by the way? One last thing, you might already do this but you can check vacuum lines easily by squeezing them (with engine running of course) with a pair of pliers closest to where they hook to the manifold or carburetor. When you pinch them, if it runs better you have isolated the problem. Then you just have to figure out where it's leaking. Usually the vac line is bad but could also be disconnected or whatever it's hooked to is bad.
Aren't cars fun!
