This is my first 4-stroke, a Saito 82. I just got an aluminum spinner today at the hobby shop for it and they told me I needed an adapter which he sold me.

I feel kind of stupid, but what parts go where? There are no instructions included with neither the spinner nor the adapter.

I assume that the parts that came with the spinner are for a 2-stroke type of shaft. Those parts are lined up under the spinner in the picture. The three parts that came with the "7mm Pro Spin Nut and Busing" set are lined up under there. And, then to the right is my engine.

Ultimately, the engine and spinner is going into my Ultimate 40.

Can anybody point me in the right direction?

Thanks,
