Pertronix ignitor for the 250 will make a big difference in its starting,idling and running.

For me, my lack of spark was a failing mercedes ignition control unit. Read my thread here:


I went ahead ditched the points and installed a HotSpark electronic ignition system. This bypassed the merceds "ignition control unit" and things have been working great ever since.
