Yea i agree just cause its rebuilt dosent mean its good to go.
most carbs sold by parts stores are junk and cost almost as much as a new holley or edelcrap.
"my opinion on the edelbrock is low

"
see if you can get a refund and then get a holley or edelbrock it will cost you about 50
bucks more for the carb and adapter plate. well worth it. I highly recomend a "510-0-804575" its new and well worth the money
