Maybe picked up a piece of trash during the change and held the needle and seat open? Pretty common for the rubber hose to deteriorate from the inside and do that type of thing, by putting the in carb filter back in you prevented it from entering the carb. Pull it back out and inspect it and you will probably see the stuff trapped in it. It sounds like I would spring for new rubber hoses in the system.

How Much fuel pressure are you getting ?
My Q - jet runs great at 7 psi. You can buy "stock pumps" that will exceed that. I run a Carter pump with an adjustable regulator.
i've also had accelator pump seals, (the skirt shaped one at the bottom) roll over and cause troubles. possibly letting fuel climb the pump rod and leak out there, but that wouldn't apply to both carburetors at once.
I would get a fuel pressure gauge and check it.

It actually ran pretty good on Friday, as long as I didn't let it idle long. I'm not sure what pressure it's making, but I'm looking for a regulator to stick on it anyhow.
Thanks for the help.
