turbo air mixture adjustment

Just put new plugs, wires, distrib cap & rotor, plus permatune CDI/matched coil. while disassembling, removed intercooler and accidentally turned air mix valve adjuster (to left of and lower left side of intercooler). how do you reset to correct setting?

Take it to a mechanic who has the test equipment.
You could buy a AFR meter, the Innovate LM-1 or XD-16 and do it yourself instead. Cheaper still Gunson do a CO meter for checking at idle.

I wouldn't risk doing a 911 turbo without proper equipment. The Innovate & the Gunson I mentioned can be calibrated.

I second Nathan's suggestion. You may be able to dial in mixture at Idle but without a proper wideband you run a big risk of getting it to run lean on bust and then.... kaboom

Yes, and also at the other end of the scale running so rich that you wash away the oil lubing the rings/bores...
