Quote: Interesting. Is it just a case of loosening off the sensor & then moving it over? How do you tell when you are at 8 degrees? S.
yes and no. it is as simple as moving the sensor over, and no because as it is layed out from the factory the sensor can only be moved about half a degree. in the previously posted picture (look closely) you can see there is an adapter under the pickup head, that is what is setting the timing. I can post a drawing of the timing adapter if you wanted to make one up for yourself. or, If you can view acad file I could PM one.
