Hello Tookmuk
In the History Record I wrote, I identified this as
a 75cc Lightweight Villiers.


I have discussed this engine here: -
https://www.outdoorking-forum.com.au/forum/u...ht-horiz-4-strokes-c1960s.html#Post84426

It's the Villiers 507H-1
This was also the JAP Lightweight 75cc

Hope this helps.
