18 ec300 jetting
Hi all,
Since I've had the latest ignition map the NEDW needle I was using that seemed slightly rich now seems a bit lean up to 1/4 throttle. Would like to know what needle to use , was considering trying the standard needle again. Maybe NEDH? Thanks Darren |

I have a Suzuki NECJ in my 18 GP300. Dunno if that helps due to the different head or not.
Need to find a table of needle specs to work out if it is richer or leaner. |

J diameter is leaner than W. Going to a H may help with your issue, or bumping the pilot up a size might too.
What clip position are you in? Have you tried going richer? |

If its lean up to 1/4 changing the needle wouldnt change that. You can try to close the air screw 1/4 turn wise or take next bigger pilot jet as Jakobi suggested.

I have the same problem with my std ec300. It work fine before the new mapping. Now i cant get it right. Either it goes very rich or When it goes fine it is detonation

With the new mapping I'm running the standard needle in the 2nd pos, 170MJ and 40PJ. 2500' and 60 - 80 degs F.
