Well...
I'm pretty stoked!
Fired the 350 up today - just a couple cranks, and it fired right up.
I am having an idling problem; fluctuating quickly up and down.
I'm guessing it's starving for fuel.
I'm thinking this because as I close the butterfly the engine smooths out and idles good.

I'm off to search the forums to see if I can find a solution.
