It's a common problem with these carbs. The cover warps over time. Get a sheet of 120G sandpaper and tape it to a hard, flat surface. Take the cover off and, gasket side down, work it back a forth on the sandpaper. The first couple of strokes will show you the high spots. Continue until you have a good flat gasket surface. Won't take much.
