Hi Cyberjack, i'm not sure if its this easy but i have a villiers 7F engine that i'm trying to date and the first 4 numbers/letters are 463X, it is on a Pace
Hello
Kye, Paul, exfarmer and all,
That's easy to get a close dating - on the 7F 463X
The 7F was made here and started to appear on AUS lawnmowers in
the last quarter of 1957. Because of the 'secret' takeover of Pace
by Victa in 1959, the Villiers were dropped in favour of Victa
engines and Kirbys for the 1960s.
The last 7Fs on Pace lawnmowers would appear for the 1961-62
lawnmowing season.
So your engine must date between those times. It is a standard
specification red painted engine. Note that it replaces the older
301X - suggesting it's very early 1960s.
Hope this helps.---------------------------
Jack
