edelbrock question

ok here we go.


this is my first carbed car. I have been driving my car and when I am cruising with my foot just on the pedal, my car bucks a little. when I floor it I have all the power I need. I am just wondering if that is a carb adjustment or would it be a timing thing. thanks

Your cruise mixture is probably a little too lean. When you get in it, you're in the power circuit, which is probably rich enough to overcome the problem.

I'd tell you how to tune it out, but I don't know that much about Performer carbs. The Edelbrock website has decent tuning tech, from what I've heard.
