Ok so the brass one is the one that the distributor goes to? I thought it was the one to the left of the idle screw. Are both of the screws idle mixture screws? The diagram that I have only shows one screw mine has two one on both sides of the pcv.
Yes they all have two mixture screws in the front. The thing to keep in mind with ported vacuum is, it has to be a vacuum inlet above the throttle plates. The brass tube is the only one on the TQ. All the others used manifold vacuum.
