360 Idle Quality

Sounds like its Lean.....
Possibly. I don't have a wideband sensor on it (yet). But, the Edelbrock carb is new, new spark plugs are a little sooty, and I got 5 mpg on the first tank of fuel. I'm thinking a little rich from not being able to idle on the idle circuit. And for the Edelbrock carb, the fuel pressure is set to 5 psi.
