After reading your comment on the engine reving high I am trying to understand what you mean. Lycoming engine with constant speed propeller? This would have a propeller governor with low pitch stop setting? Adjusting the stop screw would in return adjust engine rpm by adjusting blade angle. If I am way off base of what you meant let me know.
I agree everything should be put into the tech logs along with talking to maint about it. Alot of times mechanics will have a better understanding of what prob is and will have a better starting point.
