Howdy Folks. I'm trying to locate two glow plugs for my 47 year old DJB generator. She still runs very well after an electrical panel and fuel injector pump refresh in 1984. The glow plugs were replaced at that time as well. It's time for two new glow plugs, but as they are obsolete I can't seem to find any. Even the Champion CH41's are no longer produced. All the other so called direct replacements are really not as the threads are the wrong size. The only glow plug I thought I had found (333-0106) at a marine shop in New York was actually mismarked in stock. So what to do? If anyone has a lead on these I'd appreciate it. Otherwise I guess it's time to retire the old girl and get a new generator. By the way my generator started it's life running lights on the Alaska pipeline in 1972. Onan built some good stuff. Thanks for the help.
