Update, I thought maybe it is a vac leak? Snugged up the mounting nuts just in case.

Now for the public service announcement.
Be very careful with the front right mounting nut. Right above it upside down is a mounting screw for the accelerator pump. You can turn that screw with your wrench just enough for gas to gush out when you start the engine. All it takes is about a third of a turn or less. in less than 30 seconds of running there is a half a cup of gas on the manifold. The wrench acts like a gear against the side of the screw. BTW the idiot who designed that mounting flange didn't plan on anyone tightening the nut, you have to have someone stand on the throttle, tighten 1/8th a turn, flip the wrench over sneak under another part of the throttle tighten 1/8th a turn, flip the wrench another 1/8th go back to the other position, curse a lot, repeat.
anyway, waiting for new gaskets to get back to it.

Also, I think I found the problem. I had stupidly left the little arm for the original choke connection to the manifold heat sensor coil in place.(like an idiot) It was up into the choke/fast idle mechanism, maybe catching the mechanism? The engine heats up, the coil moves the wire bingo it's in the way to goober it up.

Anyway, I'll know soon, gaskets should be here Monday.

btw the throttle plates look ok, no binding, seating good etc..
