Can someone please provide some detailed instruction as to how an aluminum spinner and prop adapter are installed? Lots of pieces (some are left over I'm sure) but zero instructions with spinner and prop adapter. Engine is Magnum .91 two stroke spinner and prop adapter are Tru Turn.

1. Centering the backplate? Bushing included with spinner is to small for engine shaft. Purchase a larger one? Are there any tricks or bushing substitution ideas?
2. Thrust washer that came with engine. Is it used or is the steel washer that came with prop adapter substituted?
3. Prop nut and jam nut that came with engine. Where do the adapter nuts fit in?

Thanks
