Just disconnect the O2 sensor and plug the positive lead into the wire from the O2 sensor and ground you meter with the other and watch what the mixture does when you adjust it. I did this to my E21 320i to set the mixture and my car ran great and passed smog with flying colors. Its best to do this with a Fluke meter that has the sliding bar graph at the bottom.

bad man working is an unknown quantity at this point
Clockwise is rich as a rule it in to increase with injection be careful adjusting K-jet it’s very sensitive even the weight of the Allen key in the adjuster will affect it and if you turn it to fast the engine will cut-out and flood
