Hello everyone, I have searched the entire Internet for some answers . Maybe y'all can help. I just bought a 70 scout 800 b w amg 232 I6. Man trans, and a unique holley one bbl 1920 carb R4542 3509. The carb has two small vac ports I have no idea what the correct connections are. 1 large port below and angled, for the pcv I guess. Plus I don't know where the daspot vacuum comes from. The dist advance is unconnected, but don't know what to connect where. Pretty much I need a walk through on all vacumm line connections. Plus there is an unknown vacuum part located on drivers side firewall behind the engine int/exhaust manifolds. it it round and flat one line proceeding downward, two ports off the side and a threaded center neck on top. It says Holley on it's top face. What is it? Please help if y'all can. The carb has man choke btw .Thank you.
