I would be interested to know what is the dyno output of a full crank 160, as Victa never quoted HP figures for their engines but on specs ie 3 bearings, forged steel crank, quite large porting it was either designed to cope with some serious abuse or alternatively with the right carb and muffler setup some serious power output for their size. As to the famed Suzuki in my view is a just a substitute for a full crank 125. If I had a choice between a brand new Suzuki or a mower with a Full Crank 125 I think the 125 would get the gong due to its cast iron bore and 3 bearing set up.
I used a torque curve from an advertisement for a the "power unit" Victas to figure that a 160 has 3.41HP (the 125 was 2.6 I think), my 125 power unit has a carby that only opens half way, a plate about 8mm thick between the head and cylinder to lower the compression and a much more restrictive (quieter) exhaust so surely a normal one would have much more power? Who knows.
Does anyone have the torque curve for a "normal" 160?
Thanks
Hayden
