I guess the G4 came too late for the Imperial in two stroke guise.

To a degree, you probably could. But back then, when you paid a fair wack of your income for a quality machine, you were more inclined to look after it.

Plus, as they weren't seen as just an appliance back then, and people had probably grown up with ungoverned 2 stroke rotaries, which you could really get racing.

Of course in any generation there are either a**eholes or idiots who are too ignorant to know/care - just seems like the %age has increased exponentially haha. Another curve we need to flatten


Plus, with a reel mower, you have a relatively constant load - rev it up to engage the clutch and you are always have the reel spinning.

Unlike any of their rotaries - you aren't going from unloaded to plunge into 3ft high weeds. You are manicuring the lawn - its not a slasher. Plus, the engine is right up in the open air and not squished under a 1l tank of fuel with a big cowl crowding it like a rotary.

And remember, the full cranks allowable RPM was listed as up to 4200rpm (utility) - at which point, as you say, you would probably run out of fuel and maybe some ignition point bounce may be involved
