Default Timing woes...

Just completed a major tune-up by the book. The car has very little power now and after-fires.

I am ready to time the car, but cannot locate the timing mark.

It was there yesterday, and I drove the car a few miles.. and now I cannot find it with the timing light.

When I retard the distributor, the car nearly stalls.

When I advance the distributor, I can get it to idle at 750 max, but still cannot see the timing mark. If I advance all it will go the car dies.

# 1 plug with a 36 degree advance.

Where is the timing mark? or what do I need to do next?

Weights, springs, ? The distributor was not moved during the tune-up.

Did you remove the vacuum advance hose? Still seems like you should see it somewhere while moving the dist. Are you sure you have it on the #1 spark plug wire?

What year car is it? If by chance it is a 81 with the CCC still hooked up you need to unplug the 4 pin connector comming ouy of the dist. housing to set the timing. There is no vac. advance on a 81. Give us more info if you can...

Perhaps your damper outer ring has slipped. You can't set your timing if the 0* timing mark is not exactly at the #1 piston top dead center.
It can be checked easily with a piston stop like this one :

If the outer ring has slipped, you'll have to buy a new harmonic damper.
