Hello,
I have a carter performance AFB carburetor in my 428 FE, and well I noticed that when the car is turned on, i9t idels fast, and the smoke that comes out of the exhaust is to strong, making it seem like it's burning way to much gas. In other words it's too rich, and I don't know how to tune one, but if anybody has any experience with them maybe you can help me out in this matter. Also my car keeps on running after I take out the key, which I think it's because of the carb.
Thanks for reading my thread.

Kevin
