Hi Nicholas and CJ,
I'm thinking that this SC was originally fitted with a Villiers C12/2 ~ 412 engine which is a four stroke unit. Have you actually bought this machine or are you merely contemplating on purchasing it ?
They do have a bit of a following amongst us enthusiasts but nothing like the model 45. I've just added another early solid deck HK25 kirby powered 17 inch unit to my on going collection that I should really cull down but I seem to part with one and then gain another.
Since you are in Adelaide we should catch up for a brainstorming session LOL !
Cheers,
BB
