The needle setup is from an OS FP.40, using the large Evolution insert. You can also use an Enya assembly, which has a larger spray bar. You have to experiment which works best for your plane. Remember once you drill out for the larger Enya spray bar that's what you have to use, so experiment with the smaller OS. 25-.40 spray bar first.
Where did you get that needle set up, have this engine on my Nobler, yours seems to hold the setting better.
