un plug the dizzy. remove the 3 bolts. remove dizzy. installed new dizzy...itll only go on one way, so you cant screw it up. installe the 3 bolts, plug in the elctrical and then adjust to your liking, or til it idles around 6-800 rpm.
notice that the dizzy is slotted for adjustment. try to put the new dizzy in the same spot as the old one from the bolt marks
