I think the difference in the power is probably the different cams they fitted in the carbies, they were obviously trying all different types. I don't believe there was any need for a bigger motor to be fitted to any domestic mower, a 160cc 2 stroke will cut anything you can push it through, particularly if you tweek the carby and get it to function smoothly
