OZ, That is great info. I have an old K&B motor with that exact carb and no manuals. I have fiddled with it quite a bit , but have always had problems with it bogging down in flight. None of the guys at the field are familiar with it so it is everyones best guess as to what is wrong.Knowing that they have problems with thte needle turning in flightI can figure out a way tostop it . I nowknow what everything does and can work back from there.


Thanks</p>
