With the OS.10 carb from 1958 this .05 has a more proportional look.
23,690 with the 4.5x4 on the pipe no pressure tap.
30% nitro sportswerks head and plug. 8.8k idle need to adjust the set screw bit more.
Need to source another small thread (2.5mm) pressure tap, should be able to tweak to 24k ish.
I think in the air the engine design should unload very well perhaps 27k
Fuji .05 Static:
