i did read the instrutions. they made no sense. it said use the dot for straght up and use the +4 if you want to advance it and so on. but i couldn't see the speck or the +4 as in the pic.
again i would have dailed it in except that had already been done. i just redid the bottom end. it should have the big mark that is most important by the tooth and the speck by the keyway as this cloyes set. notice they even shaped the keyway like the mark so u would know which keyway to use.
