All the 300's seem to run great now ( although they ran fine before too!!)
I have a cut head too. The JD kit works well, the transition from mild to wild is too aggressive and caused by a lean mixture.

Their red needle is a H diameter from memory. N3EH#3 178 with the same pilot will make for some aggressive power.

NECW is a good choice for nice linear delivery. One step leaner on the diameter for clean delivery off idle.. and just builds. Similar in profile to the N1EF once past the first taper.
Would the bigger main jet enrichen it in the middle aswell? I have a 182 in my parts box I could try (currently running a 178).

I'll get a NECW needle too.

Thanks again
Doc


edit: ordered the NECW, will receive it probably Thursday next week :-)
