Installed my Petronix ignitor kit. How tight should the magnet fit on the shaft? It indexes just fine, but it doesn't fit as tight as I thought it would. I have a 1954 235 engine.

Also feel a little movement up and down on the distributor and can also get a little movement in a circular rotational motion, not a side to side wobble. Should there be zero movement or is a little okay?

Thanks
