Is it possible to increase hp on small engines? What I am thinking is, do it similiar to the way they increase power on vehicles. I realize most if not all small engines aren't electronic, like todays new trucks for example. I am just wondering if it is possible to "soup up" or said another way just increase performance. I had a guy tell me he could increase my 20hp Kohler on my Walker to at least a 23hp maybe 25hp. He ran 23hp on his Dixons and he was always tinkering with his mowers and he always gets a couple of thousand hours out of his machines. Anyways just curious.
