Hi vint_mow,
Welcome, a KXD4. Are you able to post a pic of your mower, I am wondering what engine is fitted to that. I have a KXD2 which has the Southern Cross four stroke fitted.
I have never seen a set of blades to suit for sale
As best as I can work out the plug is an NGK B6HS
The paint is called hammertone or hammered finish
Not sure on the starter until I see your engine
Hope this helps, there is also a Facebook group for Southern Cross Engines and Machinery. Ian Matthews runs it and he can probably supply you with an electronic copy of the manual.
All the best
Paul
