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 |

Remove it and as Rich said PB it or WD40 it. Placing it in the freezer for an hour then apply 12V. Repeat until it fully opens & closes. It will operate w/o power but takes longer to seal off when engine heat is it's only source.
