I have a Barry Grant Road Daemon 625 cfm carb that I think needs smaller jets. I get lots of black smoke whenever I really tromp the go pedal, and from what I've been able to research, going down 2 jet sizes might do the trick. Anyone have any other suggestions? I've never replaced jets in a carb before - those are inside each of the float bowl things, right?
