Hey David, these tiny carbs have TINY passages for air and gas that are hard to get perfectly clean...is the primer bulb staying tight?.. Did you remove any screws that had springs on them? .. these MUST be set at a certain number of turns out from lightly seated..(the passages these screws regulate must be absolutely clean).. If you are not sure.. take the carb to a qualified professional. ( a profession motorcycle mechanic can do the job too) did you clean the needle valve and seat very well.. clean and check the seat with a swab?..this will tell if you have got it clean and if there are any defects in the seat...
