Needle Settings for YS .63FZ-s
I know this has been asked, but what is a good starting point for the low speed, high speed and regulator for a YS .63FZ and a YS .63FZ-s?

HS start it at about 2 to 2.5 turns open Should lean it down to around 1.5
Regulator screw factory set but it will likely need a bit of a tweak. Flush with the case is the normal setting on the YS engines. I don't personally have a 63S with the reg up front. But I have helped guys set them up at the field. Factory was close.
low speed air bleed screw is about 1 to 1.5 turns from full closed.
