I was always taught- Nothing is right until the timing is dead on. Depending on octane of fuel you should be able to run 38 to 42 degrees full advanced all in by 2500 to 3000 rpm. I have seen 10to1 motors with to weak a spark missfire when under load, the spark is so weak the plugs cant fire under high compression, its like blowing the flame out on a candle.
