I have a 2003 Mule 3010 4x4 with a Mikuni carb on it. The brass plugs have been drilled out and I am in need of new jets to replace the oem pilot air jets. I ran across a discussion on another forum that talked about enlarging the jet openings to .020 and replacing the oem jets with industrial (?) servicable jets. Does anyone know where I could get replacements and/or any knowledge of this process. There isn't a whole lot of information on the subject. This carb has always been problematic.
