The one thing I don't understand about timing is this. The whole point of timing is to give the flame front enough time to travel accross the chamber so you get max burn just after TDC. Why then do you want the total timing to be completely in by 3000RPM? Shouldn't the timing continue to increase with RPM? The higher the RPM, the less time it takes the piston to reach TDC. If the timing stays the same above 3000RPM, isn't the air/fuel mixture igniting way after the piston reaches TDC.
