You have the vacuum advance system, but you chose not to hook it up? It is my oppinion of 30 years wrenching that it is necessary for a driving car.

Are you playing around with me.

Attach the hose and suck on it see if the diaphram leaks. A allen wrench adjusts the vacuum advance . Do it through the tit. If the diaphram is good hook it up to manifold vacuum. With your mechanical curve set, it should be able to adjust close enough if not right on.
