How do you figure out the hp of a lawnmower engine?
I have an old Toro Super Pro Recycler II lawnmower and I wish to use the engine to make a go kart. I cannot find any marking of the horsepower on the engine. I need to know how to figure out what the Hp is on my engine.

You could dyno test it.
5.5 hp Briggs & Stratton - Per someone else on the web with the same model. Anthony
