What a crock of rubbish that article is. "accounting for less than 10 per cent of total sales", "consumers have made the choice", so for these reasons it's not economically viable redesign the Victa 2 stroke to make it emission compliant.
Well the truth is since Briggs bought Victa, the 2 stroke became less available across the model range and unfortunately for the Australian consumers came with a premium price tag, compared to the mass produced US built 4 stroke option. This in turn forced the hand of the consumers to buy a 4 stroke. A very clever ploy by Briggs to do away with Labour intensive(or rather expensive) Aussie made 2 stroke. So yes, this resulted in 2 strokes accounting for 10 percent of sales.
Ultimately the briggs agenda was achieved, build a cheaper inferior mower with a 5-10 year lifespan. Consumerism at it's best?, I think not.
Just my 2 cents,
