RE: cc to flying weight? & what prop?
Ken... here are a more pics you asked for. And matched up a die to the threads on the crank, it was 8mm 1.0. Measured center of holes to center holes on muffler side. Across the bottom it was 11/2in. from bottom holes on both sides, they measured 11/4in. to the top hole. Is this what you need? thanks! Al
