I have the same issue, but I have kind of discounted whether it is important or not, for the simple reason that on my 29, when I am a couple clicks from the bottom of the quadrant, I think that is about all the advance my engine will handle. In other words, at that level of advance, I don't get any more benefit by going all the way down any way, so what difference would it make if I had even more range beyond that? As far as the cause, I think its due to my after-market upper plate. I have one of the newer style plates for the more "modern" point sets. I was comparing that plate, and more specifically, the length of the advance arm that connects to the advance linkage. It appears that the newer after-market plate advance arm is just a wee bit shorter than the original. That would take some of the travel away from the top to bottom range of the advance. I haven't measured anything so this is just a casual observation and nothing factual.
