My 83 (sold to JB3) was getting 25 to 28 mpg with twice the miles and I never bothered to check the timing in it.
I have lot's of parts on order for my timing light project. Hopefully it will be successful and come to fruition.

If the Fuel Injection Pump has not been touched since it left the Mercedes Factory try to imageine what would have to be worn out for there not to be enough adjustment to time the Fuel Injection Pump.
(Or someone at the Mercedes Factory would have had to install the Fuel Injection Pump without properly centering it.)
For Me the only thing that comes to mind is the Timing Chain or the Timing Gears would have to be in bad shape.
That would put the Valve Timing off also so the fix would either be a new Timing Chain and related Parts or on offset Woodruff Key.
If some previous owner has had the Fuel Injection Pump off then that could be the reason for you to run out of adjustment.
