Something wrong with my Distributor?

My distributor does not seem to be getting its full advance.

It is a 1973 Bosch, on my 73.5 911 with CIS. It is a 0 231 169 008.

When I set it at 5* ATDC (with vacuum, 2* BTDC without vacuum), it maxes out at ~25* (without vacuum).

If I set it at 36* max, it idles at 14*. (both without vacuum)

I'm trying to figure out why my car runs great, except for light throttle, where it is not perfectly smooth - everything else is great. But that's a whole other thread.

Admittedly, my distributor has coming up on 200,000 miles on it. But the shaft has no discernible lateral play, and the rotor sure seems to spring back all the way. It does have Pertronix in it.

And I may ultimately ask if anyone has a good 73 distributor, or a 74-76 (0 231 184 00x) distributor I can borrow or buy. So feel free to offer that up if you do.
