I’ve set my points on my JD to .022 in the advanced position when I retard the distributor the gap goes out to .035. I realized the breaker plate has some wear at the pivot point on the dist body and that’s where the variance comes from. I’ve been told by another JD owner that he leaves his dist in the advance position all the time and it doesn’t matter. I know if I don’t retard the spark on my 48 Pan I’m likely to have a broken leg. Should I have any concerns about this on the JD ? I haven’t started the newly rebuilt engine yet but I’m getting close.

My 25 JD always likes to be retarded a little when I start it. Some people don't do it - luckily they do not seem to kick back as hard as a panhead.

I had this exact problem. I was able to open up the points plate and made a bushing to press/loctite in. I retard my timing frequently.Dan Margolien

If you are actually riding your bike as it was meant to be operated you will be using the advance grip alongside the throttle for best performance. Steep inclines, long grades, slow traffic, all benefit from use of both controls. Fix yours.Robbie Knight Amca #2736
