Thanks MrMckay, I haven't done it myself, but that fits my preconceptions.
On what I've seen so far, the cylinder block and other core components on chondas are identical to Hondas, but the trim items (in particular, cowl, starter, air cleaner, governor plate and muffler) are quite different both from Honda, and from other brands of chonda. They mount the same way, so they are interchangeable as complete assemblies, but the parts of those peripheral components are not the same either as Honda, or as other brands of chonda.
The concept seems to be, everything is interchangeable except individual parts of peripheral, bolt-on bits. That way all of the core chonda parts can be sold as spares for Hondas, and if you have them, you can replace any of the parts of a chonda with genuine Honda parts. That is very convenient for chonda sellers, Honda owners, and chonda owners. It probably doesn't thrill the Honda dealers so much, however.
