Brilliant!
These earliest of Imperials were the better mowers.
Note the larger clutch ...

Low idle RPM, and higher torque, and a larger clutch
made the 4-strokes the better machines - in my view.

The 2-stroke Imperials were ridiculously sensitive to
throttle inputs ...because of their 2-stroke engine.
They lacked low-down torque.

Clearly, Victa understood this, and made the throttle on
their 2-stroke Imperials act as an on-off switch.

Maybe I have said too much ... eek

Very good.
