And don't forget to plug the vacuum port on the lower right. (pics were taken before you plugged that I bet) LOL
I have heard good reports from the AVS2 and Edelbrocks are easy to tune.
They are some of the best carburetors I've ever seen at running good either out of the box new, or freshly rebuilt with very little adjustment. All of them. The AFBs included. The little Street Demons are the same. I got a 625 Street Demon off Ebay for like 65 bucks needing work. It was advertised as a 750 but I knew it wasn't. It was kinda a bum listing. All it needed was a secondary air door spring and cleaned up and a kit. I put it on the truck and I really didn't need to even adjust the air screws.......but I did anyway. It runs exceptionally well and gets decent mileage for what it is.
