Going to pull my old style 99 (4 cyl) and the rules say 500 rpm over stock, so, I wanna bump it up, what is the proper way to adjust my governor to get some more rpms out of it? I know it has something to do with that clip thing on the governor spring, but I would like to know the correct way for sure. And also how far would be approx 500 rpm? Thanks in advance. I got some deere's to hunt.
