The timing is most defenitly the problem. Like the guys say you need to start out with about 8-12 degrees. Usually the advance works best on full manifold. Sometimes especialy with an auto. trans. the ported side might work better. It takes a little experamenting. The trans must be hooked to manifold vacuum. The port in the manifold behind the carb is the best place.
