Regarding the Nano .1cc diesel starting, you're not alone. I've struggled with AE .1cc, the .1cc Valentine DIVA and one D-C BAmbi. Although another Bambi was fine. I don't have the complete answer, but did find that reducing effective choke area helped with starting. From memory, the Nano has around .6 sq mm area and you may find reducing that to .3- .4 would do the trick. Even if that loses a bit of power. It gets quite critical at smaller engine sizes, when the numbers get smaller. And I'm sure some designers/manufacturers approximate badly by using common drill sizes. You may find my venturi choke size calculator on Adrian Duncan's Model Engines website useful, when assessing choke size for an engine and likely RPM for reasonable operation.
