The carb has three mounting screws and they are not symmetrical. hope this makes sence.
Break in??? With Saito??.........I light it up, set it at about 1 full turn off top RPM and let her rip. I'm starting this one out with a 20x6 Zinger. Didn't get to fly today, It will be hopefully tomorrow afternoon. I will take note of the numbers and let you know.

Miloh.
