heya welcome back.... well if you dont know where the needle is supposed to be set, check out my first post. That will get you close to where you need to be. Set your radio full rich and have the needle pretty well out say 2 turns (others more familiar with this needle may be able to correct me). You want the thing coughing and spluttering fuel when you have the throttle wide open!!! Lean off slowly from there
If you cant get it coughing and spluttering.... refer to Dave Marles post.....
