Been reading posts about damaged flywheel keyways.What would be indicators of a damaged flywheel key even if only slight damage?Prop has some damage, but I have seen worse. Could an engine run pretty descent, but only have some minor symptoms, such as maybe a slight backfire or hesitation while accelerating and otherwise seem to run strong.Not sure how much force it takes to damage one since the prop is chipped off and a lobe bent at tip.Key stronger than the prop?
