Check if it has a dipstick and if it does you dont need a gas oil mix I recommend checking the manual for the kind of oil it takes
Horse Power For John Deer JS60 080100 Push Mower
I have a 1984 Johnson 8 horse power outboard, what is the gas mixture?
5 or 6 hp.
Human horsepower is far less power full than the horsepower of a machine.
190cc equals how much horse power?
6 HP
There should be a sticker/stamp an the engine somewhere. It will give you a few specifications about the mower.
Generally it does. However a lawn mower can have a higher horse power than another brand mower, even though it has a lower cc. There is no general equation for converting from cc to horsepower for all engines and the conversion will depend on several factors such as the efficiency of combustion of the gas/air mixture, spark plug position, speed of the engine etc.
I have a push mower with a 4.5 horse on it and it uses a champion j19lm.
Yo mama fool...
If you want a push mower with good power find and older one with a 3.5 or 4hp Briggs and Stratton. Or an old Lawn0Boy 2-cycle
A 5hp craftsman engine has a compresson of 135psi
