Vacumn advance question, 18r-c dizzy

Hi guys,
I have a couple of vacumn advance units for my 18r-c dizzy. One of them I can suck air through the vacumn hole with some spare pipe and the other one I cant. The car seems to be the same with either one fitted. I've never owned a car this old so I was wondering which one is working and which one is shagged? I've already searched and didnt find the answer. Anybody ? Thanks.

the one that you can suck air through is stuffed. It will mainly make a difference to how the car behaves when driving light throttle and will also affect around town fuel economy.
If you test drive the car at WOT then it will make zip difference between the 2 (ie throttle wide open = zero vacuum).

OK mate, thanks for letting me know. I'm taking WOT as meaning wide open throttle. Will having the one that I can suck through not also make me lose power on wide open throttle as its making no ignition advance at all.

No it won't make you lose power as the distributor will still advance mechanically (by the bob weights).
