Carb Issues Poor idle after warm up?

Gearhead:

Both ports on the 1400 are timed vaccum. On the Pasenger side I pull 15psi. On the driver side I pull around 1psi. Not sure why the big difference. The distributor advance tube currently goes to the passenger side.

The float levels out-of-the-box were set at 7/16". Timing was set by my mechanic when the engine was installed. It is correct for the 302 with the 351w cam.

One thing to add: I am getting fuel flow at idle thru the front two venturis; I got the impression from Edelbrock that this is bad (a source of potential flooding). So I've relaxed the edle speed screw to see if that helps....I'll let you know.
