The rope will retract but there is zero resistance and the engine doesn’t engage at all. Thanks.Does the rope retract? Does the engine turn over, or is the starter not engaging the drive cogs?
If the engine is not turning over, it's likely the drive cogs inside the starter mechanism are sticky and not activating. Taking the recoil off and cleaning the dogs and relubricating them may get you going again. If the starter is engaging the engine and it's very easy to turn over, that would be way more ominous... and expensive!
