Default Rich Running Choke

Upon cold start up I have a lot of rich exaust. I have an article from Tuned by Lars stating to open the choke more by turning the choke pull off screw. Where the heck is this thing?

If its starting too rich then its probably the choke adjustment itself.
If its staying too rich then the adjustment or pulloff. I don't think I have a screw but bend the linkage instead. If its there It should be on the linkage coming from the vacuum diagpham on the front.
If you don't have a screw then get a book on tuning them since there is supposed to be settings for all this. The choke should be closed with a gap. This gap then can be opened with slop in the linkage. There should be a gap on the pulloff linkage and so on.
Its simple to do it with directions and the proper order of steps done.
