Check the points & make sure they are clean & opening, wouldn't hurt to put in a new set. The early transistorized ignition conversions used the existing points for a switch & over time the plastic part that rides on the cam lobe could wear away so the points no longer opened, thus giving no spark. I experienced this once on a Mallory system.
You could also try getting a whole stock system off a similar model Benz from a wrecking yard if you can find one. Don
