I'm running some aliexpress nozzles in my junk
they say they are ".30" but a .29mm pin gauge doesn't fit in there.
they do however shoot out similar amounts of fuel as my previous dss-r .360s based on smoke level alone, running them with an unchanged tune
oh, and 2 out of the 16 I bought were streaming, but I got a refund on 4 of them (as the two leftover good ones are worthless) so no real complaints on the needle seating surfaces. Only got about 3-4k miles on them running waste oil, so any long term info I get would be worthless anyways.
buying chinese is... interesting. There is no repercussions for screwing over foreigners. Even if you sue them on a six figure deal gone wrong, the company just declares bankruptcy and reopens under a different name same day.
