I'm trying to learn a little about manifold vacuum on the B28 engine. I currently have a warm up regulator that doesn't have a vacuum enrichment on my engine. If I add a CPR that has vacuum enrichment, where on the intake manifold should I hook the vacuum tubing going to the CPR? Can I tee into the vacuum line that is taken off of the rear of the passenger's side intake runner (currently goes to distributor retard solenoid)? What's the difference between ported vacuum and manifold vacuum?
