When trying to tune or fix carb problems it is best to change only one thing at a time. The first thing to check is the float level because it effects every circuit of the carburetor. When opening your carburetor for the first time it is a good idea to document all of the factory settings; float level, air/fuel screw setting, pilot jet size, needle jet size and clip location, and main jet size. You can use your air/fuel setting to determine what size pilot jet to run. Adjust the air/fuel screw to achieve the highest idle or highest vacuum reading. If you are more than 2 turns out, you need a larger pilot. If you are less than 1 turn out, you need a smaller pilot. The optimum pilot jet size will put your air/fuel screw between 1 and 2 turns out.
