Its a Rodchester carb. I tried both open and closed.The choke is a little touchy it likes t be in a certin spot. The plugs were black when I took them out. One was worse. There was enuff bild up that I could tap on it and some of the build up would fall out. I think that one was my #6 closest to the fire wall but that was before I cleaned them now they’re all black none worse then the other.Champion plugs As for the float level and the gap i dunno.
