Got one on eBay in the States - in my looking I noted they is a download available for $US32 that has all Honda engine manuals on it - you need to expand and burn to a disc to use but my DVD burner doesn't burn - reads but won't write - so didn't go that way but someone else may be interested (not on eBay but found it through Google )
Honda manuals for the first generation engines like the G65 seem to be difficult to find, but short-form workshop manuals for a lot of the later engines (including the G100 - 200, and most of the rest of the engine range) can be downloaded free from here: http://www.honda-engines-eu.com/en/engines/models_range/shop.jsp
