Replaced my Rochester B with a Carter YF today. WOW I mean WOW. It idles way better. Has way better responce. I can put to gas on and it gose. It feals like a new truck in comparison. Made a quick video on it. There is a part were it is running at the end. http://youtu.be/TIs5HOtMtfk
Thanks for the demo. I have acquired a YF but haven't had the chance to install it. But it looks like I made a good choice.
