Manula I have says use the idle air set screw but I can't find anything remotely resembling the illustration. Also remember a post about using the AFM but can't seem to locate anything.

Are you trying to set the idle speed (first attachment) or adjust the idle mixture (second attachment)? Be careful with the air bleed screws especially if you don't have some type of tailpipe sniffer to check your results. Usually the problem you're trying to correct is not based on that adjustment but the second attachment shows where the screws are. They're located under the rubber caps on either side of the AFM.

I'm trying to get the idle speed up. Neither of my 83's has what is in the illustratiion. The n/a engine has the idle air speed screw shown in the manual I have but not the turbo unit nor does it have the screw shown in the illustration. But thanks for the reply

Sorry, my bad, I didn't see the 't' in your original post.

check your other thread on this subject. I posted how to adjust it in there.
