Looks like it is about 6.5 HP
Engine size is not a direct correlation to the horsepower.
Depending on model and manufacturer, about 6.5 horsepower.
6 HP
You can not correlate cc to horsepower, it just doesn't work. Many small high speed engines may have incredible hp / size ratio, but conventional auto engines are different.
how many horse is a 190cc briggs engine
A 190cc is an type of engine.
6 hp is 190 cc here is a example........ http://www.amazon.com/Excell-Powered-Pressure-Washer-XC2800/dp/B0014T9AA2
550 ft. lbs = i hp. do the math.

A weed eater will produce anywhere from 1 horsepower up to 2.5 horsepower depending on the brand, size etc. A 190cc mower engine should have between 4 horsepower upto 8 horsepower again depending on brand, size etc. I hope this helps.
A 150cc engine is around 6HP ( I have an old lawnmower and that is what is shows on the top)... So, a 190cc engine should be around 7 -7.5 HP. I not sure who got sued, but I know there was a lawsuit surrounding cc vs. HP and that is why Briggs & Stratton engines are only rated as cc. Or that is my understanding. Hope this helps.
