An air leak will cause the engine to be lean, but the needles will keep the extra fuel/oil going into the engine, so it will still smoke. Check all the screws for the Head and backplate. Loosen the carb pinch bolt, and push down on the carb lightly as you tighten it back up. Start the buggy, and run it up to temp. Pick it up, and look closely around the head and backplate for bubbles, or fuel residue. This may help solve the problem.
