Try turning the idle mixture jet out about 1 turn, noting it's original position so you can turn it back if that doesn't help. If that doesn't do it & you are sure rest of the systems are ok, it's time to call them. At least Half the reman carbs sold are not right. Be sure there are no vacuum leaks. Do you have gaskets between the carb, spacer, & manifold, if it has a spacer?

They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
