Ok. I'm almost positive it's not an internal leak in the carb, as almost everything is new. I just replaced the intake manifold/exhaust manifold gasket and valve cover gasket, so I don't think those are it either. As far as hoses missing, it's very possible because the engine is swapped into another car. The only hose connected to anything is the line from the vacuum advance to the carb and I'm pretty sure it isn't leaking. No smog stuff, etc but all the unused ports on the intake manifold are plugged and aren't leaking. I'm not sure where to look now. Would pictures of this help?
