Edelbrock carburetor question?

I have a 1981 Chevy 1/2 ton pickup, and it's a bone stock 350. I junked the old quadrajet, and I purchased a new Edelbrock 4bbl 1405 carburetor with the adapter plate. I installed everything correctly, and now the truck won't start. It whips really fast, then begins popping and tries to start. The engine then lopes a little then dies. I tried adjusting the idle screws, but it didn't change anything. This is a brand new carb, what am I doing wrong? Thanks for the help!Edelbrock carburetor question?
if the truck ran with old carb then something wrong with the new one take it back were u got it, if u can't then check the floats in the carbs, if the carb got stored upside down the needle and seat may be stuck in the up position no fuel can get in the bowls....
Try putting the carb on your boat and then ask your question, or, you could try putting your question in the correct category.Edelbrock carburetor question?
Make sure the adaptor plate and carb base are setting on the manifold dead flat and the bolts/screws are all properly torqued. Are all the vacuum hoses/ports accounted for and connected. This sounds like an air leak, but the carb could be defective. Edelbrock ain't what it used to be. Try spraying carb cleaner down the bores while cranking it. If it wants to run it might be fuel starvation as was mentioned before. Good luck.
sounds like a major air leak somewhere thats where i would start...Edelbrock carburetor question?
Your timing gear spun.
