First I need help finding out with demon carb that I have? I can not find any part numbers on it? I think it is a Speed Demon 650 with Vacuum Secondaries but I am not sure. I have always had edelbrock carbs so if some one can give detailed instruction and how to tune this carb it would be great. I think I have it tuned pretty good, only a slight stumble under hard acceleration. It is on a ZZ4 motor. Thanks
