CyberJack, I defer to your comprehensive knowledge of the Villiers Midget engines.
My reference for that fuel/oil mix was the Owners Manual for the Midget engined Ransomes Minor Mk6, which came up in a past ODK thread we both posted to. Which just said to use 16:1 ratio. That was with SAE50 viscosity oil, too..
Cheers, Gadge
