Carb adjust??

Hey fellas.....I had my carb rebuilt not to long ago and i am not sure if it is tuned right. How do you adjust the leanness of a 4 barrel carb? I am new to this type of engine so any input will be appreciated. The carb sits atop a 454 mag.Thanks.

Re: Carb adjust??

I'm with formulaz,
Start about 2 1/2 turns out. Set idle speed. If you dont have a vacuum guage, adjust to highest rpm, then 1/4 - 1/2 turn in. Then readjust idle speed.
