73’ 318 dies under accel with new intake & carb

Totally incorrect to say that hooking up the vac adv to manifold vacuum will cause a bog. In many cases, it cures a bog because the extra timing allows the engine to make more HP & carry the load. Many factors & engine parameters to consider before making a blanket statement like that.

In the OP case, post #16, looks like gas stains around the carb, so maybe a used carb/got mileage on it? More info needed.
