Sorry its a 2010 Euro model 300 which uses the 38mm ASII (small bowl and flat metal cap) slide 7 non notched. S3 Head with black insert. Exhaust port flush with top of piston. Still large squish at 1.8mm.
The difference in the NEDJ is 2 steps leaner on the straight diameter than the N3CH and 1 step leaner then the NEDW/N3EW. I'd start by using it with a 42 pilot to compensate. I too found moving from the N3CH to N3EW cleaned up the idle issues.
So if you're using N3CH#2 I'd suggest trying the 42 NEDJ#2 172 and see how it feels. You can also get half clip adjustments (NECJ) etc.
