WilsonFlier you are correct. However it’s not worthy getting your blood pressure up.
You should know that some of us are not too concerned about break in. I turned a new Ryobi engine to 11,000 RPM today. The engine was operating on the fourth tank of 50:1 mix. It did not blow and now I know that the coil does not limit RPM.
