Tuning an Edelbrock 650AVS on a stock 340

Ok I drove with ported and with manifold vacuum. I think I will go with the manifold vacuum at 25 degrees total at idle. It was bucking very slightly in the low rpms with the ported vacuum. Other than that the car runs and drives nice either way.

Onto the next issues....

• idle rpm is often 100-300 rpm higher when I get back from a drive. Unplugging the vac advance (manifold) hose brings it down to where it is supposed to be.
• AFR is low 12s on light cruise and lean on tip in/light acceleration (15+) but it drives fine...no hesitation or bog. I'll try and enrichen the power side.
