near Cincinnati Ohio here/ ,, I seem to have the same issue on the same model engine I think this is mine hh60 105106f ser.9088c mine ran pretty good but at full throttle it just sounded like the engine was floating for lack of a better word, so only thing I did was change and set points, from that point on NO SPARK, even had a shop look at it, my question is , where can I locate procedure on how to set the gap for the coil to magneto ?
