what makes an auto/predicta and auto/predicta

Hi Sean,

The Victa 18 Auto is just automatic throttle control ,the front and rear flap control the throttle speed there
is no manual throttle control lever on the handle bars.

It was supposed to work like a governor to automatically maintain the rotary speed of an engine ,the longer
the grass was the flap controls moved more, pulling on the cables to increase the engine RPM but this system
was a flop ,didn't work very well so Victa went back to a manual throttle controller on the handle bars.

Different people have different ideas on engine numbers for an automatic .
