Another problem with the diminishing use of 2 stroke mowers is the disappearance of the once ubiquitous correctly dosed 200ml bottles or sachets of two stroke oil you simply add to the fuel can before filling up, and away you go.
I reckon a lot of the population who used to have two stroke mowers would not have chosen them if not for these bottles or the old BP Zoom fuel bowsers.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
