Failed emissions - what should timing be N/A

[vristang]

What is the factory timing supposed to be for an 87 N/A 2.3L Mustang?

I set it to 20* for emissions testing, but failed today on HC.

The Haynes manual says to go by the emissions sticker, but I can't find the sticker.

I will break out the tweecer and see if I can mess with the tune a little for my second run through emissions.

Any other suggestions?

If nothing else can someone just confirm the what the timing is supposed to be set to?

Base timing with the SPOUT connector out should be 10 degrees. I believe that with the SPOUT connector in (computer controls timing now), timing goes to aroubd 24-26 degrees at idle. Can't remember exactly; it's been a long time since I've messed with a stock computer, but I know it's right in that area. Higher than 20 degrees when running off the timing maps in the ECM.
