Yes anything can be done but will it make them cheaper, as we all know everything is controlled by the cheapest item. Sure some people will buy a quality product at a premium but the fact China makes million of cheap mowers (and this is the volume market that fall to bits) why try complicating a simple design for the smaller end of the market. The electronic ignition was a major step forward from points ignition and I doubt anybody would have argued against it but going to EFI I think would be an expensive backwards move.
AVB, how did the Robin perform, is it sweeping the market as the next big thing? All those extra components in there instead of a good old simple carby
