"anyone know how to index sparkplug gears" if you can get a hold of one of these machines in the below video then I beleive that they can help you out in cooridinating the indexing of the Plug Gears also if they need to be reground to clear the wrist and elbow pins between the rods and pistons this will help from over revving the Incurnulator arrestor. http://www.youtube.com/watch?v=pb7OWlVYYRw With out this machine you will have reindex the Spark arrestor by revolving the incapsulator froma 33 Willy's Knight, unless of course it's an flat head onversion for your Ardun overhead valve set up. Let me know how everything turns out.
