RE: OS 91SII starting Problem
Using electric started to spin motor. I have opened up the needle value, but no difference. I flew this plane about one month ago. I usually do not have to change needle valve more than two or three time a year and that might only be a click or two. This motor has been that solid. I pulled motor and took at look at o rings and made sure bolts were tight and they were. I agree it seems like it is lean, but only prime fuel would make it seem that way. Pulling tank and taking another look. It is something I am overlooking
You would think that the spinning of the prop with the electric started would draw fuel up. That being said, I am not sure it is.
Thanks for the information
