Hi Mike et al. Do any of you folks have a copy of the honda service bulletin #56? At our work we've got a honda bf225 that has a stuck spark plug and when I was reading up on things about my own bf130 I came across a partial service bulletin for the 225 but cannot find the whole bulletin. People have vaguely referred to a leak through the exhaust where cylinder #6 can have compression problems but that's about it.
