I finally got to the dial indicator on the ignition drive shaft. My dial is marked as .0005 and the difference is about 8 divisions which I make to be 0.004" so I should be within the 0.006 given by Hondaman. Any thoughts? Also given the issues with getting good points and condenser sets I am trying the basic Dynatek sensor system which I think should be less sensitive to any minor mechanical shaft run-out issues..
