I finally have to do it, clean those triggering contacts....I thought it might be a good idea to replace them as they have been triggering since 1975....I can't find any listing. So my question is: do you other 164 enthusiasts just keep cleaning them or are they available somewhere? My problem is inconsistant starting. All other ignition stuff has been replaced and I've checked fuel pressure and injectors. The engine wants to start but doesn't keep going until I've cranked and cranked, cursed and cursed and then when I finally say please it starts and I beat feet for home. The next time I go to start it she fires right up! So it's triggering contact cleaning tonight, but I'm open to other advice...glad you folks are out there....Thanks
