I've often seen folks try to replace that key, but have it slip out the back while fitting the clutch - this lets motor turn while plug is out for testing spark, but then won't turn the motor when plug is back in to start it. I've also seen a key come out and poke itself into the crank seal behind the small bevel gear and knock the seal loose.
