finally have car in "good" drivable condition after 2 1/2 years of work. Have the new Holley 600 carb on and re-jetted and is starting up and driving great. My issue is that after it gets to normal operating temp it is idling low enough that after a minute or so at a light it will die out unless I lightly give it gas. Can I adjust that out without affecting the way it starts and cold idles?
