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 |

If that fails (hopefully it won't) after several tries, you can pry the lip of the can open from around the top part. The top, valve, and spring all slide out. You may be able to use a slot-head screwdriver on the bottom of the valve to turn it, freeing it up.

All looks pretty simple. Removed the bi-metallic coil That shaft is #@%#&($ waaay stuck ! Just to be sure..... the pie shape piece is the fixed part right ? Break out the torch ? |
