RE: Prop Position
Yeah you are probably right about the necessity to do this. I just remembered reading about the influence of prop position relative to the dynamic balance of the rotating mass.The prop is the last balancing element. I am sure each engine would be somewhat different, but there was a rule of thumb to follow on positioning it if a starting position was not required. It is on a great running old Homey 30cc. Just balanced a new prop, and was toying with the position issue, I have tried it both ways and it seems a little smoother at 90 degrees. no big thing, just curious.
