Does the AAR on a 73 2.0 ever close completely ?
Does it operate on 12V only or does it rely on engine ambient temp to operate as well ? I have a high idle after adjusting timing ( with known factory timing marks ) and checking all areas for vacuum leaks. If I cap the AAR hose the idle is normal and there is adjustment left on the idle screw. The points plate moves freely with vacuum in both directions. TIA |

TIA AAR is open when no voltage present, air flows freely. when 12 volts applied, within a few minutes, but under ten minutes, it closes off completely and no air flows. |
