Hi Tjames1991 and Jack,

The spark plug was listed in the link I added last time.

I have not seen any documents to decode those Scott Bonnar id numbers.

I would think going by the handle bars on this 35 it is from around 1970 - 1973 https://www.outdoorking-forum.com.a.../85034/booklet-domestic-range-c1973.html

The 1973 brochure has no mention of using the Villiers 2 stroke ,possibly Jack has a list of model numbers to
identify this mower from the numbers.

After 1974 the Villiers 2 stroke was not used on any new mowers that I know of.

Cheers
Max
