Second: I'm sure you will get some replies soon. If it was still FI I could help a little. But with carbs, you will have to wait for the carb guys to have their coffee. |

Not a carb guy either, but welcome to the forum. What part of Georgia do you live?

Have you checked for a vacumn leak, it doesn't have to be very big to cause this.

carbs will idle faster once engine has warmed up. you must compromise with the tuning. if you set the idle at full eng operating temp, you may need to feather the pedal till she warms up. early 911s had a pull cable to set the idle high till warm
