quadrajet problem

In addition to the above, Check & make sure the that the top gasket is not binding the power valve needles - there is a slot in the gasket that the hanger has to go thru, and it can easily get caught on the power valve body when you install the top lid of the carb if you're not careful. Also, check for leaking at the fuel well plugs at the bottom. Sometimes they will leak when subjected to the carb cleaning solutions used, and most good rebuilders will seal the bottom of the well with epoxy, pipe plug, etc. Both of these conditions could cause unmetered fuel to drip or flow into the manifold, and render the adjustment needles unresponsive.
