Good post, Jim. Please note I was not speaking from experience, but only reporting on what I've read. And, I've posted this before, I really cannot understand why any plug would not work in ANY engine as long as it's the right heat range. The design is simplicity to the extreme. Yes, it has to stand up to very high temperatures and it has to be resistant to deposits that can cause fouling, but that''s about it.
Good to hear you've gotten good results with Champions. And thanks for posting the advice about the boots too. Makes sense to me!
