Here's an alternate method:
No vacuum, 10-12 deg. BTDC @ 600-700RPM
Then increase engine speed while observing centrifugal advance; advance should stop increasing at about 36-38 deg., but probably above 2500RPM.
The vacuum controls mentioned by 68_280SE were instituted primarily for emission control purposes, and even when new, and operating as designed, degraded performance, and increased fuel consumption. You can operate quite satisfactorily without vacuum.
A necessary first step is valve adjustment, and compression test, in that order.

Interesting since I will be doing this very soon. I am working on a 68 280se though.
Anyone have the specs for my car?
Any special procedure for seeing the timing on mine?
It's very interesting how many year to year changes Benz was making to these cars back then. It seems the more I read the more small differences I find in the mfi and many other things such as this.
