First off, there is nothing wrong with my 14 hp Vanguard, I just want more power. I don't need huge, just something in the 18 to 20 hp range. The question is, would I be money ahead just getting an 18 hp or make modifications to my 14? What will it take to get 18 hp out of my 14 hp? I know the difference between the 14 and 16 is the carburetor, what will it take to get the other 2 hp? All opinions welcome.
