Going back to the earlier pics , the crankcases marked 764 I believe are a Villiers 79 cc supplied only to Atco for reel mowers between about 1949 and 1960. Rope or kick start, 1454 type mower.
Just throwing in another engine number if any one can help Villiers 7F No.. is 119D 13380 engine is on a Pace 2A automatic, does this mean that because it doesn't have an X but a D instead it is imported or am I reading the posts incorrectly.
I was pretty sure you would have seen the pic, I don't know why I didn't look in History Forum thank for pointing me to it.
I noticed in a villiers manual that engines could be dated and spec'd by the engine number, do you know if there is a listing anywhere for this as I haven't been able to find anything.
