If a vacuum diaphragm is used on either side, you need to find out what is creating the switching for vacuum to be applied to each diaphragm.. Once you know that, you can use a hand vacuum pump to pull the diaphragms in the correct direct (don't apply more than engine vacuum of like 10-18" or so, just in case.
This should tell you if the diaphragms are good or if they bleed down too quick or don't hold any vacuum at all.
Does that make sense ?
