Hi Mike, If you are still experiencing the problem and if that suitable spinner included a plastic back plate then perhaps its time to upgrade to at least a spinner with an aluminum back plate. Plastic spinners especially on engines that large and up tend to give the fellows all sorts of fits and spitting props off is one of them.
