In pursuit of hunting idle, I have done the following. New plugs and wires. All new vacuum lines. Reset the ECU to factory notch on the knob. With a mirror, I found two straight notches on the back edge of the fan. The first one lined up with the #1 plug on the distributer and the dizzy notch mark. I believe that is TDC? It was (red) so I marked red on the front edge of the fan where I can see it through the hole with my timing light. The second one ~4 blades further (no color) I marked yellow line on the front edge. Removed both vac lines from the dizzy. Run the engine up to about 2K and I can get the red to line up with the notch. As the RPM goes higher it walks toward the passenger side out of sight. Pertronix rotor no points.
Is seems to me the my yellow line should be lining up as per Hanes manual. What am I doing wrong? EDIT: Okay, so TDC should not be the red, but the unpainted clear mark. The red is the 27 BTDC timing mark. |

So today I decided to turn that little screw on the MPS and see what it did. The Tangerine calibration kit is still not here and it's fabulous 80 degrees out this weekend. About a half turn and the idle is now over 1K, so dial it back with the idle screw. No more hunting!!! Okay, now able to adjust timing to red mark 27 BTDC perfect at 3500rpm. The car has never run this good in the 10 yrs I have owned it. Starts strong and instant on key turn only. Hopefully I can adjust this Volvo MPS to the correct spec for a 73 2.0L for an even finer tune.
