I was thinking about this today. My Cobra idles around 900 RPM when it is cold. It doesn't have a choke so it doesn't run very well when it is cold. By the time it warms up it idles at 1050-1100 which is too high. Why is there a difference between cold an warm idle? I have a Roush SRTW with a Bigs Stage 5 Holley carb.
