BUT that breather nipple on the bottom spits out junk all over my plane. I understand that the OS does not have that design. I don't have an OS 4 stroke but would like to know if others have this problem with their Saito and if the OS does the same thing.
I have an OS 91 with pump and also an OS 120 with pump, and both engines do not have breather nipple on the bottom. Also, none of the YS four strokes have breather nipple.
