Clean,

Thanks,

Yes, parts.

I guess I've got a lifetime supply of these things. The .15 size isn't that much in demand, even for sport.

But what are the performance demands? What prop and fuel for what RPM?

And what if I found a way to adapt the Norvel .25 muffler to it? Weight is about the same and it would be a bolt on affair. And if a part broke, likely the rod? I've got a great many miles on a couple of .06s and .074s. They don't seem to wear out but I don't push them like you might a Nelson or Rossi.
