View Full Version : TM K9B Jetting
Anybody knows what carb settings ( main jet, atomiser, idle jet, air screw, needle type) shall i use on K9B at 30'C at sea level with 98 unleaded fuel?

Alex, start with a 160 Main jet, K-22 Needle, Pilot Jet at 43 and 50, and idle jet at 60. We uste this combination at 1000 ASL and it's a good place to start.
Just remember the idel screw and air bleed screws are different. The idle screw only lifts the slide valve. The air bleed screw is just that, it bleeds air into the system, so opening it leans the mix while cloising it richens it.
Good luck, I remember what it's like to start at ground zero.
