there is a reason the factory ran vacuum advance, and no it is not for emissions, my 51 Plymouth has one.
Run one, it will help. The vacuum advance is adjustable on this distributor so I may hook it up to the ported vacuum source. The engine doesn't make a ton of vacuum, even though the cam is mild it has a 108° LSA, 60° of overlap IIRC.
