I’m experiencing prop surging on takeoff and when adjusting power at altitude. Generally it seems like it’s hunting to stabilize when I move the prop lever. Sometimes it prevents an over speed, sometimes it has a momentary over speed. A few times it oversped by 100-200 RPM and then sank below max by about the same amount before oscillating back to the setting I wanted. At static runup we managed to get it set just below 2700 with no overspeed. Is the fix simply adjusting the max RPM stop? Or do I need to go back and adjust the fine pitch stop again? Or is surging another issue entirely?
