Mixture adjustment on 3.2 911.

[Nick Triesch]

Is there another way to adjust mixture on 3.2 other than than allen screw on bottom of mass flow sensor? I was told Porsche mechanics have a way. Thank you , Nick.

Screw on the bottom is for setting CO2; screw in front is for setting idle. Then there is the spring in the box.
