When free-winding in Neutral the rpm will increase quicker and might possibly allow a higher rpm before valve float. When the rpm increases more slowly under load valve float might occur sooner.
I'll rarely and politely disagree with you John. I will agree that when free winding in neutral one may attain a higher RPM before the "FLOAT" is apparent, but the laws of physics say it has to happen at the same point / RPM.
