He adjusted the idle screws??

I DAM sure hope he pulled the carb off before adjusting that!

the idle screws should be labeled and listed on the exploded view as DO NOT TOUCH screws....

I hope its not a Holley carb....if it is he did it wrong?

Really? You don't adjust your idle mixture screws? Explain how they were adjusted wrong if it's a Holley. How would you know that?
