And can't give it all it's got it will bog down after about 3/4 peddel down. But for the most part it's back running like it use to hell it's better then it use to run. Got it non running lol and when you say manifold vac where is that located. I'm not very incline on this kinda stuff but love monkeying with it.

Manifold vacuum is usually any port below the primary throttle shaft on your carb.
Now it sounds like you might be flooding a little due to the popping inside the carb.
Look inside while it's idling. You shouldn't see any raw fuel.
