I like the power delivery of the NIEF but it's too rich off idle. Got the N1EG and there was an improvement but had to go down on the pilot jet (previous 40). Good transition off idle into middle range and soft hit when WOT. Still a bit tricky to idle but a bit better than before. Air screw still bares almost no influence on idle, might have to go down again on the pilot jet.
Tried the N3CJ #3, MJ180, PJ40 but too much of a hit when WOT.

If you want smooth power but the N3CJ#3 ran clean (with a mid top hit), then consider NECJ#3 (and 2 sizes leaner on the main). It's much more linear.
