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.

Nobody's arguing WHERE to put vacuum advance that I saw. And yes, depending on WHERE his initial timing is, WHERE he has the advance hooked can have an effect. Changing from manifold to ported and back REQUIRES that the initial timing be changed to compensate for each different vacuum port.

....or do yall do it backwards down under? I do hear toilets flush the opposite way.
