When I went to set the timing to the proper 8 degrees of advance. It ran terrible. Called Ken Henderson. He said that the outer part of my harmonic dampener had rotated. I DID NOT know that the Olds unit could do that. I was aware of other engine. So if at some time your timing was set to a moved mark. It could be affecting the timing. Thus reducing mileage. I'm thinking that I may have set my timing retarded the last time due to this. There are indexing marks that GM did when new. New one is $42. Bob Dunahugh 78 Royale
