Hi all - I have recently accquired a 1977 RRC 3.5 running and driving project with original Strombergs and hope someone can help me. I'm quite new to these and am mystified as to what this is and what it should be connected to if anywhere? The lower end comes from the LH carb and the open end does have vacuum when engine running. The ignition advance is connected seperately and works so it isn't that.
Many thanks.....Peter
