I have had a hard time finding the correct plugs for it. In the seventies they were the RJ12Y Champions this one came with the smaller "peanut" plugs. When I tore her down for rebuild I threw the old plugs away, like who knew they would have come in handy for finding plugs? Lesson learned on that one. OK, yes they would have tapered seats the thread size is 1.25. So what am I looking for in number for spark plugs? And yes I didn't find an answer looking through the previous posts.
Many thanks
