The first 10 minutes for a Saito are supposed to be at 4,000 rpm with the throttle at 1/4 to 1/3 open, not full throttle at some super rich setting.
PS, I'm going to break in this Saito .65 on Monday using Wildcat 2/4 which has 10% nitromethane and 18% full synthetic lube. It will be about the 5th (Including a 90TS and 100T) Saito I've broken in on full synthetic and all have turned out perfect. The choke shown is gone and it now wears a velocity stack.
