Hi all.
I'm just trying to Identify this motor on my model 40. As I'm trying to source a new head gasket for it.
Attached are pics of the little beast.
Thanks in advance!

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.
