Edelbrock Carb question

[myersjeremy]

Got a sweet deal on an Edelbrock performer intake/carburetor($50) from a guy at work. No problems with the intake. The carb is totally different. I put the sucker on and the truck starts right up but is flooding like crazy. I adjusted the mixture screws and that didnt seem to make a difference at all. I split the carb in half and on the side of the carb that would sit on the passengers side there is a loose spring just sitting in the housing. Its a larger size spring but there doesnt seem to be anything to hook it to. Is there something missing????
