Use or don't use vacuum advance on distributor???????????????????

OK, you tune the engine to work with the vacuum advance connected. You don't "get" the distributor to work with manifold vacuum, it already will.

Right but how? What needs to be done? Let me start it over because we are frustrating each other and that is not my intention so for that I apologize. I do want both problems fixed. If I can use the vacuum advance I want to but the only option is with manifold vacuum I do not have ported vacuum. Only reason I wanted to adjust the vacuum can is to make it take more vacuum to advance the distributor. Right now it advances at idle. I am idling at 850. If I hook it up the things sounds like a tractor.
