Oh well Gedeon, I am making sure I do not give my engine a hard time. I run it nearly daily for just a minute and it seems to run better each time. To start on the first attempt I open up the throttle to half and the needle valve 1.5 turns. As soon as it starts I throttle it back to idle.
Today I finished off the wooden base by drilling the mounting holes and giving it two coats of teak oil.
Also today I finally started work on the fuel tank lid. I did not start it earlier because I was still working out how to machine both sides. The lid is only 4mm thick. Started off by machining the top part of the lid (photo 1). I left a longish spigot on purpose so that I can use it to hold it in the chuck when machining the other side. With the parting tool I removed some excess material on the side before parting off (photo 2).
Turned it over and holding it by the spigot I machined the bottom of the lid (photo 3). Now all that remains is drilling a 3mm hole through the spigot and milling off the excess spigot. I also need to drill a vent hole in the lid.

Finished off the lid by drilling the 3mm hole through the boss and then milled off the excess boss material. Then drilled a 1mm vent hole (photo 1).
Then manufactured a small brass knob (photo 2) to hold the lid in place. Final photo is the tank bolted to the carb banjo. It looks exactly like the original float chamber except for the brass knob at the top of the lid.

Well, finally, I am happy to say that the final piece of the jigsaw is now finished and fitted.
The pedestal to support the external oil reservoir has been done. Nothing special, made from aluminium. No photos were taken during the making of this part but I took a photo of the finished pedestal in its place.
Hopefully, weather permitting, I will take some photos of the finished Kiwi using natural light and post them here as a final installment to this build.

The engine runs on unleaded petrol (gasoline) and no gaskets were used as suggested by Westbury.
