The P-38(reduced accel pump flow) will allow a richer clip position, try EKN#4. The #45 pilot can run lean with the stock air jets. This will sometimes allow turning the screw all the way in. It doesn't always mean you need a smaller pilot jet at all the way in on the fuel screw. See how it runs with the #45 and 2 - 2 1/4 turns out.
