600 edelbrock secondary bog.

Hmmm. I'll start from square one then. I'll pull the carb back off and clean all the passages out and recheck the float levels again. Hopefully its just some crud stuck in a tube or air bleed somewhere.
if you could take some pics and post them, that might be helpful. What is the link to the online manual you were using? I could take a look and refamiliarize myself on your particular carb model.
