Timing 73 2.0L D-jet, Help Options

[steuspeed]

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.

On my 74, the white mark is TDC. The red mark is the advance you want.

You want the distributor hold down snug when you adjust timing, so it takes some effort to turn it.

The car needs to be revved to >3500 for full advance with the vacuum lines removed - this will give you full advance - I suspect this is where you are going wrong.

Regarding the hunting idle...Try running full rich (clockwise) on the ECU knob, turn it counterclockwise one notch at a time until it begins to hunt, then go back clockwise one notch. If full rich doesn't cure the hunting, you may need to install a ballast resistor, which were used on the 1973 model. Fiddle with this after setting the timing.

Good luck & keep us posted.
