Brickman, I am by no means a carb guru, but I've messed with enough Carter/Edelbrocks to be fairly familiar with them. You can drill out the jets on them where you can't on a Holley, but I don't think that is your problem. I believe your problem is in the primary discharge circuit and/or float adjustment/float drop. That is a pain to adjust. I would suggest having the carb boiled out and rebuilding it to insure there are no contaminates in it.
