1. wont idle at proper rpm, look for a vacuum leak

I'll check for vacuum leaks tomorrow, and as for the choke it is an edelbrock 1406 carb w/electric choke, no heat riser off of intake manifold. I am running the vacuum advance off of the full-manifold vacuum port on the edelbrock carb since this is the port that is recommended for non-emission controlled vehicles. I have been getting lots of static about this because my friends have been telling me that I should running of of the timed vacuum port. Am I ok to have it running off of the full-manifold port? What is the difference between ports? Could this be contributing to the problem?
