What model edelbrock is it? You might need to change the springs in the top that hold the enrichment circuits closed. If its a larger cam with low vacuum the stock springs wont work. If I recall correctly, the springs hold the needle down (closed) and when vacuum drops they open up. The less vacuum you have the lighter spring you will need to use.
You would need to order the calibration kit for whatever model carb you have.
