Yo mama fool...
190cc equals how much horse power?
There should be a sticker/stamp an the engine somewhere. It will give you a few specifications about the mower.
A 5hp craftsman engine has a compresson of 135psi
5-6 horse power
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
I'm assuming its a riding lawn mower of some type. Our own lawn mowers of this type have an alternator in them that keeps the battery charged
You should always have 20 fluid ounces of oil in a Briggs and Stratton 5.5 HP lawn mower. This equals out to roughly 1.6 quarts.
Not sure how to answer your question with the right answer. However, lawn mower spark plugs come in three sizes: 5/8, 3/4 and 13/16.
replace it
That will vary for each make and model of mower.
