I have a Sun distributor machine. When I first got it I thought I wasn't using it properly or that there was something wrong with it. The timing would reach full advance at whatever rpm and then at high rpm it would loose a few degrees at max rpm. Talking with other distributor machine owners, they have found the same trends. I'd still like to hear a explanation for why this happens. You would think centrifugal forces wouldn't allow it

That said I don't think I have ever seen 10 degrees only a few.




Tom do you remember what RPM were you seeing this happen at ?
