On your '85 you will probably be able to twidle that screw in and out all day long without noticing much effect... seems to be a function of high miles on the engine and an aging air flow meter. but don't run out and replace the air flow meter, i did on mine and it matter not a whit. :( The dealer here in Bemidji just laughs when I ask about adjusting the darn thing, he hasn't found that CO screw to be very effective on the wasserboxers. if you have a digital VOM, try setting the CO to give you .5 volts on the O2 sensor (search earlier posts regarding this) -dan
