so you can lean out the fuel being burned. i think the pilot jet is for idle plus some throttle.maybey it's a little to big for you temp. and elevation.

If it's within the first 1/4 it's the pilot circuit - too rich. Smaller jet or adjust the fuel screw (turn it in 1/8th of a turn at a time.).
If it's above 1/4 and below 1/2 try dropping the needle 1 clip before changing out the main jet since it seems to run fine in the higher rpm's.
