car is acting real weird now
Now it bogs down before it takes off. only at certain times though it doesn't always do it. It happens if I give it light throttle does that mean maybe my idle mixture is off?

Did you post this somewhere else? Old w/no replies, just wondering.
I'm no Edelbrock expert, but it sounds like your transition from idle to power isn't quite right, not the idle mixture itself. Perhaps someone more familiar with your type of carb can take a shot at it.
