Re: I could use some Quadrajet Guru help

Some things to check are fuel pump pressure. Too much above 5psi and it may be pushing past the needle valve.

Also when doing the rebuild did you check the well plugs for leaks? Qjets were known for leaking well plugs causing symptoms like you have. Anytime you rebuild one you should separate the top and bottom and if you suspect they're leaking either re-epoxy or install the aftermarket well plugs.
