Hello everyone, me and my son are working on the ole gal and I want to adjust the quadra bog .. We have it running but running really rich , my son figured he would adjust it well I think it's running worse. Does anyone know how to adjust one ? I thought it was bottom out the idle needles and turn them out 2 1/4 turns and then adjust one side at a time to get the most vacuum is that correct? Also do I have to plug every port coming off the carb except for the one I'm using for vacuum gauge? It would be great if I could get this thing to purr again after sitting so long..
