Re: setting mixture with dwell meter 700

Scott,

Assuming your ignition timing, idle and 02 sensor are all within specs, here's how Bosch advised me to adjust my AMM. It isn't described in Bentley this way, but my O2 sensor/AMM are properly calibrated and my emmision levels are extremely low for that year (or so I've been told). You'll need a Digital Multimeter (DMM).

Make sure engine is fully warm, then shut off.

With 02 sensor UNPLUGGED, connect meter to single signal wire off sensor to read low DC range voltage.

Slowly turn adjusting screw at AMM either clockwise or counterclockwise to bring voltage in the .3-.8v range. Signal should fluctuate. And THAT'S IT!

Now on my 84 clockwise is richer, cc is leaner. Yours may be different. Bentley has it the opposite, so I'm not sure.

The resistence value on MY LH2 AMM for optimal mix is 304ohms. Yours will no doubt be different.

Good luck.
