First off if you dont have an ear for it, get a tach. Your rpm range is right, but that has to coincide with the right prop. Using the tach start leaning it out until you dont see any gain in rpm and then back down 300-500 rpm. If your engine speed is out of the range you want, then use another prop to get this right. When I move to the low end adjustment and if I have made some pretty big adjustments down there, I will redo the high end as there is a handshake agreement between the high and low and that is how the mid range is set; making sure both are happy together. It might take some back and forth to get right, but when it is, you wont touch anything except in big seasonal changes.
