You are right. The fact of the matter is that we do put a CM-6 plug on our engines, and that is how we ship them. When we write the specs, we explain that it has to be a CM-6 'type', just for informational purposes, but that is what we use.

Regarding NGK, they are not banned in China, as a matter of fact they have a manufacturing facility there. Now, with the earthquakes in Japan, we are all uncertain about some parts' availability, so we might have to resort to Germany for bearings and so on. Hopefully we can do that without affecting our cost too much so our clients don't get affeted at all.

Again, thanks for your kind comments, and sorry if I made it sound as if I felt you were picking my engine appart, because I really didn't.

Regards
