85 4x4 blazer 2.8

I just installed a new carb rebuilt by holly...reason was the old one was leaking bad and would not idle without stalling....with new carb it idle's fine now but it bog's out and tries to stall when i take off...2.8 5 speed
any idea's?

idle runs richer then when you open throttle valve a bit to allow more air in ... i'm guessing you need to adjust mixture screw one way or the other.
