Drifter, you may have helped me. i have a CD-15 im trying to get going and it did the same thing. i havent gotten a chance to yank the carb off again and check the vents. Although a little odd as when it was apart to put the new kit in i blew all the holes out with compressed air, i did notice a mud dauber nest outside the carb in one of the crevasses so…. ill revisit this tomorrow.
