Default RE: Prop hard to tighten

Maybe you are using some kind of this nut:

If you are using this kind of nut you also have to use the washer that came with your engine. This kind of spinner nuts has a relative shorter thread, so maybe you are experiencing a lack of thigtness regarding the longer crankcase bolt.
